## What it is
The staging repository for TypeScript 7.0, a native Go port of the TypeScript compiler (tsgo/tsc), offering dramatically faster type checking and builds. The port is complete and development has moved back to microsoft/TypeScript, with this repo archived.

## Use cases
- type-check typescript projects 10x faster
- replace tsc with a native compiler
- speed up typescript builds in ci
- run a faster typescript language server in vs code
- try typescript 7 native preview

## When to choose
- you want the fastest available TypeScript compiler and type checker
- you have large codebases where tsc watch/build times are a bottleneck
- you want to use the official TypeScript 7 native toolchain

## When to avoid
- you rely on the TypeScript compiler API, which is not ready in the native port
- you need full feature parity with TypeScript 6 in every edge case
- you want an actively developed standalone repo - development now lives in microsoft/TypeScript
