TypeScript 7.0 ships first stable Go-based compiler, delivering 8x-12x speed improvements
TypeScript 7.0 has shipped its first stable release featuring a complete rewrite of its compiler from TypeScript to Go, delivering 8x-12x speed improvements on full builds. This marks a major milestone for both TypeScript and the Go programming language, as the rewrite leverages Go's native code speed and shared memory multithreading. The performance boost is significant enough that it could dramatically improve developer workflows, with build times potentially forcing even Slack developers back to their keyboards.
