5. Example how to Vue and Laravel Work Together

1. Backend (Laravel):

Laravel handles the database, Authentication, API endpoints, and server-side logic.

Example API route for a post application:

Route::get('/login', [LoginController::class, 'index']);

Route::get('/user', [UserController::class, 'index']);

Route::get('/posts', [PostController::class, 'index']);

2. Frontend (Vuejs):

Vue.js fetches data from the Laravel API and dynamically renders it on the page.

Example using Axios:


      async handleGetPostsList() {
        const response = await axios.get('/api/posts');
        console.log('response data: ', response);
    }

Conclusion

Vue.js provides an interactive and flexible user interface, while Laravel offers a robust and comprehensive backend platform. Combining Vue.js and PHP Laravel allows you to leverage the strengths of both frameworks to develop modern, efficient, and maintainable web applications.

Anti-Patterns That Every Developer Should Know

Understanding Anti-Patterns in software development

In software development, it's important to write code that is not only functional but also clean, maintainable, and scalable.

However, developers often encounter many challenges while building systems, and in some cases, they may fall into common traps known as anti-patterns.

These are poor programming practices that seem like good solutions at first but, over time, lead to inefficiencies, hard-to-maintain code, or even system failures.

In this article, I want to explore some well-known anti-patterns in software development and provide examples in code to help you understand how to identify and avoid them.

1. Hard-code, Magic String and Number

Hard-code means hard-coding some values and some logic that needs to be changed directly into the code, such as database connection, some configuration...

Magic string and magic number means hard-coding a number, a magical string, without clearly stating where that number/string comes from, or what it is...

For example, the code below is both hard coded and uses magic numbers.

Solution: This Anti Pattern is easy to handle. Just don't hardcode the config values (but read from the config file or know the environment), separate the magic numbers into separate variables, or write more comments.

The code after the fix is much easier to understand, right?

2. Callback hell

The concept of the callback is certainly not strange to JavaScript coders, especially when processing asynchronous JavaScript functions (like in NodeJS for example).

However, if we overuse callback functions without proper coding methods, our code will become extremely complicated and difficult to read.

Solution: to avoid callback hell, there are several approaches that make asynchronous code more manageable and readable. Two common solutions are Promising and Async/Await.

Using Promises: A Promise is an object representing the eventual completion (or failure) of an asynchronous operation and its resulting value. Promises allow you to avoid nested callbacks by chaining .then() methods.

Using Async/Await: Async/Await is a more modern and cleaner approach to handling asynchronous code. It allows you to write asynchronous code in a synchronous-looking manner, making it much easier to read and maintain.

3. God Class/Object

A God Object is an anti-pattern where a single class or object is given too many responsibilities, making it overly complex and difficult to manage.

This is a common mistake among students who are working on projects, or in projects that are too old, and written by inexperienced developers.

Gob Class means a super-huge, Divine Class that can do anything, so it is called God. This mistake occurs when developers put too many features into one class.

Solution:

Following the Single Responsibility principle in SOLID, each class should only have 1 Responsibility.
Refactor the code gradually, separate the class into smaller classes, and group functions/data that are often used together into a separate class.

4. Copy-Paste Programming

Another common anti-pattern is copy-paste programming, where developers duplicate code instead of abstracting common functionality into reusable functions or classes.

This is a pattern of writing code once, the next time you need to use it, copy the old code, and modify it a bit to make it run.

In the long run, this will cause the project's code to swell. The code is repetitive, and when editing or fixing bugs, many places will have to be fixed. If you forget or miss something, you will miss bugs.

Solution:
The simplest way is to separate the code that needs to be used into a separate function, a separate library to use.

5. Spaghetti Code

Spaghetti code refers to code that has a tangled and convoluted structure, often because of excessive use of global variables, lack of proper design, the flow is roundabout, extremely difficult to read, and difficult to fix.

The reason could be that the coding team doesn't have a specific design, or the developer is lazy so they code haphazardly. Or because the requirements are constantly changing and overlapping, but the modules and designs are not updated, so they also overlap!

Solution:

This is the most difficult Anti Pattern to solve completely! Because it is not only related to the code but also related to the design of the modules in the system
The easiest way is to destroy and rewrite when you understand the original logic, but it will take a lot of time and may lack requirements
You should gradually refactor the code and separate it into small parts. You can redesign the modules if necessary.

6. Golden Hammer

The Golden Hammer anti-pattern happens when a developer uses a familiar tool or technology to solve every problem, even when it's not the best fit.

For example, a programmer was assigned to develop a website project that required a simple UI and required fast response, with no animation.

However, he chose a UI library that he was familiar with even though it was quite heavy, had many unnecessary configurations, and was difficult to use for beginners.

Using the wrong tool for the job can lead to inefficiency, poor performance, and scalability issues. It's essential to choose the right tool or technology based on the specific needs of the problem.

Solution:

Evaluate the problem carefully and choose the right technology. For instance, if you need to store large amounts of unstructured data, consider using NoSQL databases like MongoDB or Cassandra instead of traditional relational databases.

7. Premature Optimization

Optimizing code is the process of editing/rewriting code to reduce size, limit input/output, increase execution speed, and reduce the amount of hardware needed.

Sometimes, optimizing code too early (not knowing where it runs slowly, and which part to optimize) is completely unnecessary, it also makes the code more complicated, harder to read, and harder to debug.

Solution:

Don't optimize too soon or too quickly. Ask yourself if the code needs or is worth optimizing.

Conclusion

Avoiding anti-patterns is crucial to writing high-quality, maintainable code. By recognizing and addressing issues like God Objects, Spaghetti Code, Lazy Classes, Copy-Paste Programming, and the Golden Hammer, developers can build systems that are easier to maintain and extend over time. As software development practices evolve, it’s essential to constantly improve our approach and learn from past mistakes

What is IT Staff Augmentation - A Flexible Solution to Scale Your Workforce As Needed

In recent years, the demand for IT staff augmentation has been on the rise among organizations worldwide. This growing trend can be attributed to several factors, such as increasing expenses in hiring skilled software developers, growing necessity for agile development practices, and the constant push towards becoming more adaptable, quickly scalable teams.

In support of this surge in the trend, market data points out, according to Verified Market Research, the IT staff augmentation service market was valued at USD 299.3 billion in 2023 and is estimated to reach USD 857.2 billion by 2031, reflecting a strong 13.2% compound annual growth rate (CAGR) from 2024 to 2031. In other words, it is projected that the market may indeed reach threefold of its current worth by the year of 2031, a clear indication of the fact that IT staff augmentation is quickly taking root across the world.

With operational experience of over 20 years delivering IT staff augmentation service and software development outsourcing to the clients around the globe, we at ISB Vietnam have seen first-hand how such solutions can turn around the scaling and innovating capabilities of a given organization. In this article, we shall take a close look at the IT staff augmentation basics, weighing some pros and cons before sharing a few best practices. By the end, readers will have a far better understanding of how working with a seasoned IT staff augmentation company can help meet their ever-evolving business needs.

What Is IT Staff Augmentation? Definition and Meaning

IT staff augmentation is a versatile solution for staffing temporarily external IT professionals with particular skills that your organization needs. Usually, you take help from a company that provides skilled developers, engineers, or other IT experts. These specialists become part of your internal team while you manage the project. Thus, you benefit from skill sets while retaining project management control.

The real benefit of IT staff augmentation services is agility and cost-effectiveness. You scale up or down your workforce based on project needs but without costing much more than a full-time hire or going through a long process of hiring. Such agility and flexibility aid faster-turning industries amidst frequently changing market trends.

Staff Augmentation vs. Project Outsourcing

When companies need external help for an IT project, they generally consider two main options: staff augmentation or project outsourcing. With project outsourcing, the vendor typically takes complete ownership of the project, including all management responsibilities. By contrast, IT staff augmentation keeps project management in-house. Your organization retains leadership of daily operations and decision-making, while the external team members integrate with your existing workflows.

Key Benefits of IT Staff Augmentation

When projects are fast-paced and susceptible to changing developments, IT staff augmentation frequently gives a lot more flexibility than project outsourcing. Especially where the organization already has an in-house development team and prefers to manage project management internally. This allows you to have temporary support from outside experts added to your existing team, hence reacting to changing requirements much faster and running projects in a very agile manner. Mentioned below are the three crucial reasons that demonstrate the reasons for the widespread acceptance of IT staff augmentation services.

1. Quick Access to Highly Specialized Talent

In case there is a lack of certain IT skill sets in the team, staff augmentation simply offers a direct path to top professionals around the world. Rather than wasting valuable time in posting job ads, interviewing, and onboarding new employees, you will quickly source what you need, such as experts with the necessary talents and experience.

When you partner with IT staff augmentation companies, the capabilities of the organization can ramp up very quickly. This allows your business to remain on track without sacrificing quality or violating delivery deadlines.

2. Optimized Costs and Flexible Resource Allocation

Another major benefit is cost optimization. Hiring full-time employees for short-term needs can lead to excessive overhead due to salaries, benefits, and recruitment expenses. In contrast, IT staff augmentation requires payment only for the duration you actually need the additional resources.

This pay-as-you-go model helps keep budgets predictable and manageable, giving you the freedom to expand or contract your team in line with project demands. In other words, you can sidestep the financial burden of maintaining permanent staff without risking a shortfall in workforce capabilities when project requirements intensify.

3. Continuity in Management and Operations

By integrating outside specialists into your current team, you can retain your existing processes, tools, and management style. In an IT staff augmentation setup, your organization maintains control of day-to-day project oversight. You direct tasks, set priorities, and coordinate development efforts just as you would with an entirely in-house team.

This stands in contrast to project outsourcing, where a significant portion of oversight is delegated to the vendor. For organizations that value hands-on control of critical projects, staff augmentation offers a middle path—bolstering your team with expert talent, yet preserving your internal workflow and decision-making authority.

Potential Drawbacks of IT Staff Augmentation

While IT staff augmentation offers clear benefits, it also presents certain challenges. Being aware of these potential issues can help your organization make the most of this approach. Below are two key considerations:

1. Projects Needing Extensive Internal Knowledge or Long-Term Commitment

IT staff augmentation tends to be most effective for focused or shorter-term projects with well-defined goals. If a project demands deep organizational context—such as complex business processes—or spans multiple years, the additional onboarding and knowledge transfer may outweigh the advantages. In such scenarios, forming a dedicated internal team or pursuing a different staffing model could be more sustainable.

2. Balancing Internal and External Resources

Relying too heavily on external IT staff may dilute your organization’s internal expertise and reduce control over critical operations. While staff augmentation can provide a flexible boost to your workforce, it’s essential to maintain a strong in-house foundation. This balance helps preserve core institutional knowledge, ensures continuity, and guards against the risks that come with sudden changes in external resources.

In all knowledge and with the foresight that any pitfalls may bring, staff augmentation can be strategically and smartly approached to provide a substantial level of flexibly without the drawbacks.

Best Practices for Successful IT Staff Augmentation

Using IT staff augmentation services effectively is more than just hiring more staff. A clear plan is needed, beginning with a clearly defined intention and ending with the support for your extended team. The following six best practices will serve as a guide:

1. Set Goals and Objectives

Before delving into IT staff augmentation, ensure a clear view of what your project requires in terms of needs, timelines, and challenges. As mentioned in the sections in “Potential Drawbacks of IT Staff Augmentation”, there are instances where it would be fitting to resort to other means, such as hiring in-house employees or outsourcing the whole project . Such clarity will position you properly in deciding whether IT staff augmentation will suit your needs.

2. Set the Skills and Competencies Needed

Once the goals and objectives have been set, accurately outline the technical and soft skills that your extended staff will need. Apart from the basics: budget limits and duration of a project, also consider having specialized technical expertise, industry knowledge and language skills, and personality characteristics such as flexibility and communication skills. This all-encompassing view will assist in identifying candidates who not only meet the required technical fundamentals but also harmonize with your in-house team.

3. Choose the Right IT Staff Augmentation Partner

Finding a reputable IT staff augmentation company is crucial. Different providers offer different talent pools, specialty areas, and resource availabilities. Your perfect partner should provide the exact mix of skills and experience you are looking for.

For instance, at ISB Vietnam, we leverage our heritage as a Japan-affiliated company based in Vietnam to provide top-tier developers who possess high-level technical expertise and strong quality control skills. We also excel in English and Japanese language support, enabling us to deliver IT staff augmentation services to clients worldwide.

4. Conduct Interviews with Prospective Team Members

Even with a trusted partner, it’s wise to interview any candidates who will play a major role in your project. Just as you would with full-time employees, use this opportunity to verify their technical skills and assess soft skills like communication, teamwork, and adaptability. If you have a large pool of candidates and can’t interview everyone, focus on key contributors. This approach helps ensure a strong cultural fit and alignment with your project goals.

5. Clearly Define Roles and Responsibilities

Once new IT staff are inducted into your team, it is wise to set out roles and responsibilities in clear terms. The clarity in each person's role in the whole set of things for the project will enhance accountability, prevent confusions, and simplify workflows. The principle also promotes cohesiveness within the team such that everybody knows how best they can contribute toward the success of the project.

6. Offer Ongoing Support and Integration

After your augmented team members have onboarded, maintain a supportive environment. Temporary staff often face unique challenges, such as understanding existing processes and team dynamics. As a manager, keep an open line of communication to ensure they receive the guidance they need. By proactively offering assistance, you can help them integrate faster, enhance productivity, and address any minor issues before they escalate.

By following these best practices, companies can optimize the impact of IT staff augmentation services, ensuring that temporary team members become true collaborators.

Conclusion

Due to increasing pressure to produce more and greater innovations at a higher speed and efficiency, IT staff augmentation has emerged as one of the most effective means to add resources to development teams on short notice. Whether niche talent is needed for a project with time sensitivities or you would like to scale technical capabilities with less commitment than full-time hiring, IT staff augmentation services can fill such gaps on short notice and in a cost-efficient manner.

However, be sure to approach this model with a focus on clear objectives, demarcated roles, and a solid onboarding process. By identifying exactly what skills you need, connecting with the appropriate IT staff augmentation company, and providing continuous support to augmented team members, many of the hurdles that characterize short-term staffing solutions can be subdued.

Larger factors should guide the decision regarding staff augmentation. In the case of short-term, specialized needs, which require quick turnaround times, staff augmentation can enable agility and foster innovation. For longer-term projects, a more permanent in-house team or some form of outsourcing may work better. Careful, thoughtful weighing of these factors will help ensure that your staffing choices drive the sustainable growth you're after and keep your projects on track.

Onshore vs. Offshore: Definition, Differences, and Key Considerations

Pros and Cons of Onshore and Offshore Development: Choosing the Right Model for Your Business Growth

Vietnam’s Population and Workforce Provide Abundant IT Talent

According to Key insights and trends for software developers in Vietnam 2024-2025, Vietnam boasts a robust IT workforce, with approximately 560,000 professionals employed in computer science and IT-related fields. This is bolstered by about 55,000-60,000 students joining computer science and IT-related majors every year, adding to the tank of skilled software developers and IT specialists.

This abundant IT talent is supported by several factors, with Vietnam's demographics being one of the first. Vietnam's population continues to rise, and by December 2023, the population reached nearly 100 million people, making it the 15th largest population worldwide, and ranks 3rd in Southeast Asia.

Year	Vietnam’s Population
2021	98.51M
2022	99.46M
2023	100.3M

Population pyramid of Vietnam

Vietnam's youthful population, as depicted by its population pyramid, makes its median age fairly young at 33.1 years as reported by the CIA’s The World Factbook. For perspective, on the other end of the scale, the median age in the U.S. is 38.9, in the U.K. 40.8, in Germany 46.8, in Singapore 39.4, in Australia 38.1, and in Japan 49.9. This youthful age profile, where the larger segment of the Vietnamese population belongs to the age relative to the working force, provides a solid advantage for the country in promoting its IT sector.

For software developers and IT professionals, it is essential to keep pace with the changing leaps in technology. The younger workforce is generally flexible, eager to learn, and quick to embrace new tools and practices. Moreover, with Vietnam having a high percentage of under-20s, it guarantees a steady supply of working-age talent for many decades forward.

As highlighted in the article Key insights and trends for software developers in Vietnam 2024-2025, talented individuals in Vietnam increasingly seek careers in the IT sector, drawn by attractive salaries and growth opportunities.

Looking further ahead, Vietnam’s IT service revenue is forecast to expand to $3.2 billion by 2028.

IT Services revenue by segment in Vietnam

The growth in the IT Outsourcing segment of the four segments—Business Process Outsourcing (BPO), IT Consulting & Implementation, IT Outsourcing, and Other IT Services—is particularly noteworthy. Vietnam's IT Outsourcing revenues are projected to grow dynamically from $0.7 billion in 2024 to $0.83 billion in 2025, $0.98 billion in 2026, $1.13 billion in 2027, and $1.28 billion in 2028, almost doubling in size within a period of four years.

This growth comes through a possible commercial advantage of Vietnam as one of the most captive destinations for outsourcing. While global demand for IT solutions continues to increase with a shortage of qualified IT professionals, Vietnam has strategically positioned itself as a reliable and cost-competitive partner for businesses round the globe.

Given those trends, Vietnam is poised to further expand in software outsourcing and offshore software development. The advantage of providing high-quality IT services at affordable prices makes it remain an attracting country in meeting the global demand of IT.

Average Salaries and Rates for Software Developers in Vietnam

As noted earlier, Vietnam has a rich, highly skilled IT labor force and serves as a fast-growing destination for IT outsourcing. One major reason for Vietnam's attractiveness is the cost of IT talent.
The report mentioned the average gross salary for software developer in Vietnam is around $1,300 per month. Including various costs such as management costs, the average hourly rate for software developers in Vietnam is around $20 to $40. Naturally, these rates vary depending on the developer's level, years of experience, skills, and tech stack etc.

Like this, the salary and rates levels of developers in Vietnam are low when compared to Western countries. This feature opens the door for strong cost competitiveness of Vietnam and a cost-effective alternative to having local developers or outsourcing to local software companies in many parts of the world.

While labor costs remain subdued, the quality of software developers is on an upward trend in Vietnam, which reflects advances in the experience and skill levels of the workforce. By outsourcing to Vietnam, offshore development offers an acceptable blend of quality and expense because of the competitiveness of developers there.

The balance between level of technologies and IT workforce cost-effectiveness puts Vietnam in an advantageous position to be one of the leading software outsourcing and offshore development destinations. Companies can access skilled developers across a wide array of technologies at a fraction of the cost compared to Western markets.

Conclusion

Vietnam's IT sector is one of the most remarkable success stories. With over 100 million people and still growing, the median age in Vietnam is about 33 years, presenting a young workforce with a high proportion of working-age people. This demographic advantage, together with the fact that 55,000-60,000 computer science and IT-related students come in every year, provides long-term talent supply for IT professionals.

In 2024, approximately 560,000 experts are already working in IT-related fields, and this number is expected to increase more in the coming years. With both private and public initiatives churning out IT talent in droves, this human resource from Vietnam has indeed been highly developed to continue attracting attention globally.

Consequently, Vietnam continues to see a boom in professionals with high-level specialized knowledge and practical experience in software development and IT.

Factors that account for this phenomenal growth:

Government Policies: The Vietnamese government recognizes IT talent development as a national strategy by actively supporting the IT sector within national development plans.
Competitive Remuneration: The IT and Tech industry in Vietnam has been recognized for paying above-average salaries compared to other industries. This financial advantage serves as a magnet for talents to pursue careers as software developers or work within IT companies.

These factors set the base for the high-quality and skilled talent within the industry and is a major contributor to the rapid growth of the technology industry in Vietnam.
Vietnam software developers are acknowledge for their work ethic and being highly skilled. Vietnam has consistently ranked among the top 10 countries for best offshore software development and outsourcing services due to the vast talent pool and competitive rates.

A few examples stand out:

In the Global Services Location Index of Kearney, Vietnam came in sixth among the biggest countries for software outsourcing services in 2021.
As per Accelerance's 2022 Global Software Outsourcing Trends and Rates Guide, Vietnam ranks at the second spot among its Southeast Asian peers when it comes to being a software outsourcing destination.

In fact, Vietnam's IT sourcing revenue has been experiencing significant growth and is projected to increase substantially from $700 million in 2024 to $1.28 billion in 2028, nearly doubling within just four years.

Such praise is a testament to the continuous rise in both the quality and quantity of software developers based in Vietnam, furthering its standing as a favored destination in global offshore software development and software development outsourcing.

Next, we will dive into the features that distinguish Vietnamese software developers and the most common Tech Stacks according to the report above.

Age Distribution, Years of Experience, and Level Distribution of Software Developers in Vietnam

Vietnam is a fast growing economy characterized by a youthful population, with an average age of 33 years. Such demographic trends are reflected in Vietnam's software developer workforce, largely shaped by the younger generation.

Age Distribution

Age distribution of developers in Vietnam

As per estimates, in 2024, the age profile for the majority of Vietnamese software developers is 25-29 years of age, accounting for 29.3% of the total. Right after them comes the age group 20-24, which with 28.8% includes young adults. This means that over half or 58.1% of all developers in Vietnam fall into the 20s age group. The remaining proportions include 30-34 years (15.8%) and 35-39 years (10.2%).

While younger developers still dominate, the overall age distribution has moved upward gradually from 2022 to 2024. The proportion of developers who are 15-19 and 20-24 has decreased, while the groups of 25-29 years and 30-39 years have seen increases. This constitutes a maturing software development workforce with a growing number of experienced professionals.

Years of Experience

Years of experience of developers in Vietnam

The same pattern is displayed in the skill levels of the developers. In 2024, most developers had 2 to 3 years of experience, at 28.8%, followed by those with 0 to 1 years of experience, at 22.1%. Together, developers with 0 to 3 years of experience account for 50.9% or around half of the total work force. After this, there is a consistent upswing of developers from midlevel to senior level: 4 to 5 years (18.4%), 6 to 7 years (11.7%), 8 to 9 years (7.9%), and 10 to 11 years (6.0%).

Although the first-year workers dominate the field of software development today, the steady mainstream growth of skilled personnel also indicates a transition of the developer workforce to a more competent level-suitably equipped to handle streaming, large-scale, complex projects.

Level Distribution

The History and Popularity of Programming Languages over the Last 40 Years

In our last article “Most popular programming languages in 2024”, we dived into the platform TIOBE and its latest data in relation to the most popular programming languages. We discovered that Python had attracted overwhelming popularity in 2024 because of the exploding demand for AI and data science. Besides Python well-known languages such as C++, C#, Java and JavaScript have maintained their strong positions in the programming language rankings of 2024, proving their long-term popularity.

Today, we will once again draw on index data from TIOBE. This time we will present an overview of shift in programming language popularity over the past 40 years. From 1984 until 2024 to gain a deeper understanding of the historical trajectory of these programming languages. We believe this article is important to understand vital technological milestones that been a big part of shaping the digital landscape as we see it today.

TIOBE Index

The TIOBE Index is one of the most recognized platforms globally for understanding programming languages and their popularity. It has been trusted and relied upon by developers, businesses, and researchers for many decades. To get a fuller insight into the TIOBE Index, its gauges, and why it still commands such respect within its sectors, we suggest that you refer to the in-depth overview enlisted in the link below.

The History and Popularity of Programming Languages over the Last 40 Years

In this section, we will go deeper into how programming languages have developed in popularity over the past 40 years. We will look at the period from 1984 up until 2024 as reflected by the TIOBE Index.

Programming Language Popularity Ranking from 1984 to 2024

Programming Language	1984	1989	1994	1999	2004	2009	2014	2019	2024
Python	-	-	23	24	7	7	7	3	1
C++	13	2	2	2	3	3	4	4	2
C	1	1	1	1	1	2	1	2	3

Objective-C	-	-	-	-	38	27	3	10	35
(Visual) Basic	4	5	3	4	4	5	41	-	-

* Average popularity ranking for the 12 months of each year

* "(Visual) Basic" originally encompassed all Basic dialects, including Visual Basic. Since 2011, after splitting these variants into distinct categories (Visual Basic .NET, Classic Visual Basic, etc.), the major implementation, Visual Basic .NET, is now referred to simply as "Visual Basic."

* SQL, despite its age, was only added to the TIOBE Index in 2018 after it was pointed out to be Turing complete, resulting in a relatively short presence there.

1984 would be the year that really mattered for the IT industry and Apple. It was the year when Apple launched the first personal computer called Macintosh, with a graphical user interface (GUI). In its wake, Microsoft rolled out its very first operating system, Windows 1.0, in 1985. This time also marked an era for PCs as we know it today and is symbolic starting point for the 40 years journey.

A broad look at the TIOBE Index trends from 1984 to 2024 reveals that the most popular programming languages have changed dramatically in tandem with available computing resources, evolving software development methodologies, and shifting industry structures.

Back in 1984, the programming language C was dominating. Remarkably, even after four decades, C still ranks near the top of the programming language ranking in 2024. However, Python has now ascended to become the undisputed leader among today’s most popular programming languages.

This long-term trajectory underscores a fundamental pattern: a steady shift from low-level to high-level languages, and eventually toward specialized languages thriving in cutting-edge domains.

Next, let's take a look at the changes of popular programming languages in each decade from the 1980s to the 2020s.

1980s–1990s: The Era of C, Fortran, Lisp, and Ada

While C remained strong, holding the No.1 spot in 2004 and almost maintaining it in 2009, Java surpassed C to claim the top position in the TIOBE index by 2009. C++ enjoyed strong popularity, placing third in both 2004 and 2009 and claimed its status among the most popular programming languages. Meanwhile, as Windows dominated the PC market, Microsoft’s C# saw increasing growth, climbing to sixth place by 2009.

2010s: The Rise of Python

The technologies of data science, AI, and machine learning propelled the 2010s and changed rankings in popular programming languages. Python, ranked seventh in 2014, gushed to third by the TIOBE index by 2019. Its mighty repositories, frameworks, and unmatched versatility in data, AI, and Python scripting all played a big part in this rise.C retained the big number one spot in 2014 and the second place by 2019. During that time, JavaScript became solidified as the de facto front-end development language, whereas Go found its place as a cloud-native. Languages like Objective-C were briefly to spike due to iOS development, soon to yield prominence to the new laurel, Swift.

2020s (until mid-2020s): Python’s Unstoppable Lead and the Enduring Legacy Languages

By 2024, Python had firmly established itself as the leading language in the programming language ranking, leaving its nearest competitors far behind. The unrelenting demand for AI, machine learning, and data science propelled Python to become the industry’s “common language,” bridging developers across countless domains. Meanwhile, legacy languages like C++ and C remain popular mainstays, and Java, C#, and JavaScript—pillars of the 2000s and 2010s—continue to command strong positions.
Languages like Fortran, Ada, and Lisp, developed in earlier eras, still play vital roles in niche sectors where their unique capabilities are indispensable. In the 2020s, cutting-edge technologies coexist with these legacy systems, reflecting the rich and diverse landscape of modern programming languages.

Conclusion

In the 40 years from 1984 to 2024, as technology has evolved significantly, the computing and business environments have also changed dynamically. Following these changes, various programming languages have risen and fallen.

When hardware resources were a constraint, C, Lisp, Ada, and Fortran were widely used, when the demand for commercial enterprise applications expanded, Java was one of the most popular programming languages. And in the AI era of 2024, Python had firmly claimed the top spot in the programming language ranking.

After 2025, which programming languages will become more popular in the ever-innovating IT ecosystem? It will be important to keep an eye on the ever-changing trends in programming languages.
