Why C# Won the 2023 TIOBE Language of the Year and What It Means for Developers
C# has become the 2023 TIOBE Programming Language of the Year, topping the index with a 1.43% rise, overtaking Java in popularity, while the article examines the latest rankings, growth trends of other languages such as Dart, TypeScript, PHP, and offers insights into predicting future top‑20 languages.
C# Crowned TIOBE Language of the Year 2023
In the highly watched TIOBE Programming Language Index, C# surged in the preview month and officially became the 2023 Programming Language of the Year, confirming its leading position in software development.
Historically, C# earned its first "Language of the Year" award. Over the past two decades it has consistently ranked in the top‑10 and now shows the largest annual gain (+1.43%). It is narrowing Java's market share and gaining traction in web‑backend and game development (thanks to Unity). C# remains free, evolves steadily, and may soon surpass Java.
Besides C# , the world’s best language PHP also surged, recording the second‑largest increase (+0.40%) in the top‑10.
Top 10 Programming Languages (2002‑2024)
Interesting question: Which languages will break into the TIOBE top‑20 in 2024? Julia briefly entered the index in 2023 but fell off. I predict the next winners will be Dart (Flutter) and TypeScript. The latter is already widely used in industry but has not yet cracked the index.

Explanation
The programming language community ranking is an indicator of popularity trends, updated monthly. Rankings are based on the number of global engineers, courses, and third‑party vendors, incorporating search engines and technical communities such as Google, Baidu, Wikipedia, Bing, and others. Detailed calculation methods are available at the official TIOBE definition page.
Note that the index reflects popularity, not language quality or the amount of code written in a language.
The ranking can help you assess whether your programming skills stay current and serve as a reference when choosing a language for new systems.
