TypeScript is moving to Go – 10x faster

Guys, this is HUGE! TypeScript is being rewritten in Go, and it’s official. Compilation will be up to 10x faster (yes, I had to double-check too).

What’s happening?

1. Stable release planned for mid-2025
2. Full build system & language service by the end of the year
3. The current JS-based version will continue until TypeScript 6.x, but TS 7 will be Go-native

Why Go?

Microsoft says it’s all about performance. The JS-based TypeScript compiler has hit its speed limit, especially in large projects. Go compiles faster, uses fewer resources, and scales better. In theory, we’re looking at an INSANELY fast compilation.

But I have some questions:

• What happens to existing tools and integrations?
• How will this impact the ecosystem?
• Will there be new plugin APIs?

Any downsides?

There have to be some. Even if they deliver a blazing-fast Go compiler, the ecosystem is deeply tied to JS. The big question is how they’ll maintain both versions and how smooth the transition will be.

At Hyand Group , we always keep up with the latest tech trends, and this shift could seriously impact frontend development workflows. Our team is already discussing what this means for our projects—should we start preparing for TypeScript 7 now?
