TypeScript compiles 10x faster with Go native port

TypeScript 7.0 replaces the JavaScript compiler with a Go-native implementation, cutting build time by 10x in tested environments.

Summary

Compilation speed directly affects dev loop friction on large projects. A 10x speedup reduces CI/CD bottlenecks and local iteration time, compounding savings across teams.

Implementation verdict

Replaces existing TypeScript 6.x compiler. Requires dropping in v7.0 as a drop-in upgrade. Worth switching immediately if you're on a large codebase—the benchmark claims real-world validation across orgs.
