devblogs.microsoft.comA 10x Faster TypeScript - TypeScriptEmbarking on a native port of the existing TypeScript compiler and toolset to achieve a 10x performance speed-up.

In case you missed it, TypeScript 7 is a complete 10x faster version of the compiler & language server. It's a full port to parallelized native code. It runs faster, uses less memory, and is more stable than ever before.

It's simple to get started npm install -D typescript@7 Then run `npx tsc` as usual for a new native experience.

The 10x is real for many projects, and the speed improvements make a huge difference for teams at scale. TypeScript 7 drops time in CI, and minimizes delays in editors like VS & VS Code. That makes every part of the developer inner loop feel snappy.

The new codebase has been battle-tested by many teams (and entire companies) using it in production for over a year now. In fact, in the editor TypeScript 7 is *more* stable than TypeScript 6, with fewer crashes and lower memory usage.

TypeScript 7 has all the editor features you love, like auto-imports, find-all-references, expandable hovers, inlay hints, code lenses, linked editing, semantic highlighting, import sorting, and more. They're just a lot faster now.
