GitHub says TypeScript passed Python and JavaScript in August to become the most used language among its 180M+ developers; India added 5.2M developers in 2025
short, smart, and snappy. Packed with info on the seismic shifts happening in how people build software. Check it out! [video] @infiniflowai : Thrilled to announce that RAGFlow is featured in the GitHub Octoverse 2025 Report as one of the fastest-growing projects by contributors! 🚀 Huge thanks to our amazing community for the incredible momentum! Check out the full report: https://github.blog/... @github #Octoverse [image] LinkedIn: Luke Hoban : TypeScript is the #1 most used language on GitHub 🤯. — Thirteen years after it was first released, TypeScript has overtaken Python as the most used language on GitHub. … Bluesky: Sedat Kapanoğlu / @ssg.dev : typescript surpasses javascript — in popularity because apparently, AI coding agents work better with strongly-typed languages.
Context & Ripple Effects
GitHub’s language rankings have shifted repeatedly: JavaScript led its 2020 reporting, while Python moved ahead in GitHub’s 2024 platform snapshot, which also recorded rapid growth in contributions to generative-AI projects. TypeScript’s ascent had been visible earlier in cross-platform language-usage research.
The latest change matters because it puts a typed JavaScript variant ahead of both of the recent leaders on a platform GitHub says now serves more than 180 million developers. GitHub’s report also identifies India as a major source of new developers, broadening the population behind these usage signals.
First-order effects
- TypeScript gains a clear adoption milestone on GitHub, while Python and JavaScript lose their recent positions at the top of the platform’s usage ranking.
- GitHub’s reported 5.2 million new developers in India expands the platform’s contributor base and increases the weight of developer adoption outside its established markets.
Second-order effects
- Tooling vendors, project maintainers, and employers that use GitHub activity as an adoption signal have more incentive to prioritize TypeScript support, documentation, and hiring pipelines.
- Python remains tied to the prior surge in generative-AI project contributions, so the ranking change sharpens the distinction between broad application-development activity and AI-centric repository activity rather than settling which ecosystem dominates all software work.
Third-order effects
- If the ordering persists, typed JavaScript could become a more central default for web-facing and full-stack development, concentrating ecosystem investment around TypeScript-compatible tools and libraries.
- The result also underscores that language leadership is increasingly fluid: GitHub-scale developer growth and shifts in what is built on the platform can reorder adoption faster than legacy popularity rankings suggest.
The trend: Developer-platform growth and AI-era project creation are reshaping programming-language rankings toward ecosystems that combine broad web reach with stronger type tooling.
