GitHub’s Octoverse 2025: TypeScript Surges as AI Reshapes Developer Ecosystem
GitHub's developer base expanded at a record pace in 2025, with one new coder joining every second—pushing total platform users beyond 180 million. The growth coincides with TypeScript dethroning Python and JavaScript as GitHub's most-used language, fueled by AI-driven development tools and demand for typed languages in production environments.
TypeScript's strict type system has proven ideal for AI-assisted coding, with 80% of new developers adopting GitHub's Copilot within their first week. The Octoverse report underscores how AI isn't just accelerating code production, but fundamentally altering language preferences across the software industry.
