TypeScript Gets a Go Rewrite: 8x Faster!

Microsoft is developing a native TypeScript implementation using Google's Go language. This promises dramatic improvements in editor startup speed, build times, and memory usage, making it easier to scale TypeScript to large codebases. The plan involves porting the TypeScript compiler, tools, and codebase from JavaScript to Go. Microsoft aims for a mid-2025 preview of Go-based tsc command-line type checking and a feature-complete Go implementation by year's end. Visual Studio Code users will experience significantly faster editor performance, including an 8x improvement in project load times and instant comprehensive error listings.
