TypeScript technical fellow Anders Hejlsberg introduces TypeScript 7, the native code (Go) port of the compiler and tooling that runs roughly 10x faster than TypeScript 6.

Watch a live compile of the 2.3M-line VS Code codebase drop from 50s to under 5s, see how shared-memory concurrency uses every core, and check out the new LSP-based language server with near-instant references, squiggles, and startup — all with 99.99% compatibility with TypeScript 6.
