Programming language recommendation

1. Java: None The Arguable Winner

As it was a year ago, Java remains the most popular programming language. According to data from TIOBE, Java has topped the list more often than any other language for decades. Many well-known companies use Java to develop software and applications, so if you happen to use Java, you definitely don't have to worry about finding a job. The main reasons for Java's popularity are its portability, scalability and large user community.

2. Classic C

As one of the oldest programming languages, C still tops the list, thanks to its portability and its adoption by technology giants such as Microsoft, Oracle and Apple. . It is compatible with almost all systems and is well suited for operating systems and embedded systems. Since the runtime environment is relatively small, C is the perfect choice for keeping such systems lean. It is highly recommended for beginners to learn C. It is actually the lingua franca of programming languages and has spawned equally popular derivative languages such as C and C#.

3. C continues to dominate

This object-oriented programming language was developed in the 1980s and is still used in many systems from desktop web applications to server infrastructure. . C remains popular due to its flexibility, high performance, and ability to be used in a variety of environments. Jobs in C often involve developing desktop applications for performance-intensive tasks. Mastering C provides a deeper understanding of the programming language and helps gain skills in low-level memory processing.

4. Python: On the Rise

Over the past 15 years, the popularity of Python has steadily increased. In the past few years, it has been able to rank among the top 5 of the TIOBE index. As the primary language behind some of today's most promising technologies, including artificial intelligence, machine learning, big data, and robotics, Python has amassed a huge fan base in recent years. You'll be surprised how easy it is to learn Python, which is why many experienced developers choose Python as a second or third language.

5. C#: The darling of game developers

C# is a modern object-oriented programming language developed by Microsoft to compete with Java, which was widely used by commercial software developers at the time. It is designed for developing applications on Microsoft platforms and requires the .NET Framework on Windows to work. As in the previous year, C# maintained a stable position with no major changes in rankings. Almost any application can be developed using C#, but it is particularly good at Windows desktop application and game development.

6, Visual Basic, NET

Visual Basic and NET continue to maintain sixth place in the index as last year. It is one of Microsoft's OOP languages that combines the power of classes and runtime environments based on .NET Framework. Derived from VB6, it is good at developing GUI applications, simplifying tasks for programmers and increasing productivity. For programmers, in addition to Web services and Web development, VB and NET also provide a quick and easy way to develop desktop applications for the Windows platform.

7. PHP for Web development

According to TIOBE, PHP ranks seventh in TIOBE’s most popular programming language rankings, replacing JavaScript as the more popular scripting language. . PHP is mainly used on the server side for web development, accounting for about 80% of the total number of websites. Facebook originally used PHP, and its role in the WordPress content management system made it popular. PHP provides several frameworks, such as Laravel and Drupal, to help developers build applications faster with higher scalability and reliability. Therefore, if you are looking for a job in web development, PHP is a good choice.

8. JavaScript is essential

The usage of JavaScript has declined this year, and its ranking has declined compared to last year. But now all software developers use JavaScript in some way. Used along with HTML and CSS, JavaScript is essential for front-end web development in order to create interactive web pages and dynamically display content to users. More than 90% of websites use this language, and it is also one of the most user-friendly programming languages for beginners to start with. So, if you master JavaScript, there is no shortage of opportunities. However, you need to learn other supporting languages and frameworks to become a professional front-end developer focusing on desktop and mobile application or game development.

9、SQL

SQL took ninth place, achieving significant growth, after all, it failed to rank among the top 20 programming languages in the TIOBE index last year. Although other database technologies exist, this standard query language for managing databases has dominated for the past four decades. The reasons are its simplicity, reliability, ubiquity, and active community that go a long way in keeping this open source language alive. Compared with other languages, SQL is generally easier for beginners to learn; in terms of career development, high-paying positions such as data analysts require SQL knowledge.

10. Programmers like R

In recent years, the demand for the R programming language and the number of people using it have increased rapidly. It can be clearly seen from the TIOBE ranking that R's ranking has risen four places: from 14th to 10th. For data scientists, R is the first choice for statistics, graphical representation, and visual analysis of data. It has become a big data tool, used in machine learning and some areas of scientific computing. The scope and prospects of the R programming language are promising, and it is definitely a stable and lucrative career option for those interested in data science.
