Developers Shift Toward TypeScript With AI

GitHub's Octoverse 2025 data (reported August 2025) shows TypeScript surpassed Python and JavaScript to become the most-used language on GitHub, driven by AI-assisted workflows; TypeScript grew 66% year‑over‑year while JavaScript grew 24% and shell scripting in AI-generated projects jumped 206%. The report links widespread Copilot adoption—80% of new developers use it within their first week—and over 1.1 million public repositories using LLM SDKs to a convenience loop that changes tooling choices.
