What are the world’s most popular programming languages? Learning the answer to that question can help you determine which languages to learn (and master) next.

A new report from DevSkiller highlights some of the most popular programming languages and tech skills worldwide. Here’s a breakdown of the languages that everyone seems to be using; if you know anything about programming, there shouldn’t be any surprises here:

“In the first half of 2024, the most popular programming languages tested on the DevSkiller platform were Java (18 percent), SQL (15.5 percent), and JavaScript (14.2 percent),” read a note accompanying the data. “This is a shift from the end of 2023, where Java and JavaScript held larger shares at 27.2 percent and 19.2 percent, respectively, while SQL was significantly lower at 8.6 percent.”

Why are these languages so popular? In simplest terms, JavaScript is the backbone of web development, and critical for creating dynamic web pages that users expect. Tech pros and developers everywhere rely on JavaScript for everything from online applications to animations.

Meanwhile, Java is an immensely popular language for a broad range of applications, from massive enterprise systems to Android apps. Many developers like its cross-platform development capabilities.

SQL (Structured Query Language) is a programming language used to manipulate databases; it's the backbone of data storage and analytics. In organizations big and small, SQL is crucial in ensuring data integrity, efficiency, and cybersecurity.
