TypeScript 6.0
The last TypeScript release built on JavaScript
TypeScript 6.0 is the last release built on JavaScript — and the bridge to TypeScript 7.0, which is being rewritten in Go for native speed and parallel type-checking. This release modernizes defaults (strict mode on, ESM-first, ES2025 target), adds built-in Temporal API types, Map.getOrInsert, and RegExp.escape, and deprecates legacy patterns that won't survive the native port. If you write TypeScript, the migration window to the native era starts now.
TypeScript 6.0 is a Open Source company. It launched on Product Hunt on Mar 24, 2026, with 156 upvotes. Adamlead has 1 person on file at TypeScript 6.0.
