The TypeScript team has decided to port the compiler and toolchain to Go language to solve performance bottlenecks in large codebases and improve overall TypeScript Go performance.
Performance Improvement: By rewriting in Go language, TypeScript's compilation speed and project loading speed will significantly increase. Official data shows that editor startup project loading will be 8x faster, and most build times will be reduced by 10x
Version Roadmap: The TypeScript team plans to release a native command-line type checking implementation by mid-2025, and a full-featured project building and language service solution by the end of the year. TypeScript 7.0 will be the Go-based native version, while the TypeScript 6.x series will continue to be developed based on JavaScript
This is an official video released by the TypeScript team, detailing the TypeScript Go project (Go language port of TypeScript) and how it solves performance bottlenecks, expected to make TypeScript approximately 10x faster.
