A 10x Faster TypeScript
TypeScript is undergoing a major performance improvement by porting its compiler and tools to a native implementation. This effort aims to improve editor startup, reduce build times by 10x, and decrease memory usage. Initial previews will be available by mid-2025, with a full feature release by the end of the year. The native port promises significant speed gains in editor responsiveness, command-line builds, and will support more advanced development features.
