According to JetBrains’ State of Developer Ecosystem Report 2024, JavaScript remains the most-used programming language globally. With 61% of developers relying on it to build web pages, JavaScript continues to dominate the programming landscape. The report highlights that despite the rise of other languages, JavaScript’s flexibility and deep integration with web development frameworks keep it at the forefront of modern development.
Python, while not surpassing JavaScript in usage, holds its place as the second most popular language, with 57% of developers using it for various applications, particularly in data science, artificial intelligence, and web development. Other widely-used languages include HTML/CSS, with 51% of developers using them for web design, SQL at 48%, and Java at 46%. Notably, TypeScript, a superset of JavaScript, ranks fifth with 37% of developers using it, showing its growing appeal due to its ability to enhance JavaScript code with static typing.
While JavaScript and Python remain dominant, the report also points to languages that are gaining momentum, with TypeScript, Rust, and Python showing the most promising growth. TypeScript usage saw a 3% increase from the previous year, reflecting its appeal for building more reliable and scalable applications. Similarly, Python’s growth is also notable, with a 3% increase, as it continues to be a top choice for developers working on AI and machine learning projects. Rust, known for its safety and performance features, also saw a 1% rise, making it an increasingly popular choice for system-level programming.
The report, which was released on December 11, is based on responses from 23,262 developers worldwide who were surveyed between May and June 2024. This comprehensive analysis offers insights into how programming languages are evolving, with JavaScript continuing to lead but new contenders like TypeScript, Rust, and Python gaining significant traction in the developer community. As the tech landscape shifts, the report highlights the growing importance of these languages in various sectors of the industry.
