How TypeScript Got Faster in 2025: A Look at the Go Port
A recent announcement revealed that TypeScript is being ported to Go, bringing a remarkable performance boost: by the team’s estimates, memory usage is cut in half, and compilation speed is up to ten times faster. In this overview, we’ll explore why Go was chosen, what benefits developers are already seeing, and what to expect in the future.

Why a New Compiler?
TypeScript has become the standard for countless projects, yet the community increasingly requested improved build speed and reduced memory consumption. The native Go version promises exactly that:
- Reduced memory usage — by about 50%.
- Increased speed — up to 10 times faster than the original JS compiler.
The team has rewritten around 80% of the functionality so far. Some features (like JSDoc and JSX) are still pending, but the new compiler should be mature enough for most daily use by the end of the year.
Why Go?
- Performance and memory management. Go was originally designed for high-load systems that need both speed and efficient resource management.
- Smooth migration. TypeScript’s extensive use of recursive data structures maps more naturally…
