Microsoft has released TypeScript 7.0 Beta, featuring a complete rewrite of the compiler from TypeScript to Go that delivers approximately 10x performance improvements over version 6.0. The new compiler maintains full semantic compatibility while offering significantly faster build times and improved developer experience. Extensive testing with major companies confirms the stability and performance gains of this foundational change.
Background
TypeScript is Microsoft's popular typed superset of JavaScript that compiles to plain JavaScript, widely used in large-scale web development. Previous versions were written in TypeScript itself and compiled to JavaScript for execution.
