TypeScript is now the most used language on GitHub in 2025 Yep, you read it right, TypeScript overtook both Python and JavaScript. Its rise illustrates how developers are shifting toward typed languages that make agent-assisted coding more reliable in production. It doesn’t hurt that nearly every major frontend framework now scaffolds with TypeScript by default. Even still, Python remains dominant for AI and data science workloads, while the JavaScript/TypeScript ecosystem still accounts for more overall activity than Python alone. #AI #TypeScript #Python
Glad to see developers increasingly understand the importance of a good type system. In isolation TypeScript is probably one of the best languages out there - the thing dragging it down is it's association with JavaScript (and the fact JavaScript is still the most common compilation target). Deno and Bun made some great progress in divorcing the two, let's hope for a greater acceptance.
Very interesting, but the real question is the machine generated TypeScript being compared against human generated JavaScript? If you were to look at the Machine Generated HTML Bloat that Microsoft Word spewed out that would have a very different SLOC count than a hand coded HTML document. There is nothing magical about Typescript, it has to transpile to Javascript and that's what the browser understands (like WASM). There are plenty of other Java->Javascript or C#->Javscript libraries for type safety that handle the conversion over to Javascript. That's what we are talking about here is are we seeing the end to hand coding Javascript? Just like C /C++ made hand coding assembler obsolete. Will be very interesting to see if AI prompt engineering deprecates entire software stacks.
