TypeScript is Moving to Go – HUGE Performance Gains!

TypeScript is making a bold move for performance—switching to a native compiler written in Go! This change promises a 10x speed improvement in compilation, better concurrency, and a more responsive development experience. The TypeScript team experimented with Rust and C#, but ultimately, Go was the best choice for maximizing efficiency. This transition isn't just about the compiler—it also affects the entire TypeScript toolset, including the language server, leading to faster IntelliSense, quicker type checking, and a smoother VSCode experience.

In this video, we test the new TypeScript compiler vs. the current JavaScript-based compiler, benchmark the speed improvements, and explore what this means for developers. Will this be the biggest TypeScript upgrade ever? Let’s find out!
