TIL: TypeScript 6.0 is the final major version built on the original JavaScript compiler. TS 7.0 will be a ground-up rewrite in Go. The goal is a 10x improvement in check/emit performance for massive codebases. Migrated a large project today—the 6.0 bridge features make the transition smoother.


```bash
tsc --version # Version 6.0.2
tsc --stableTypeOrdering # Preparing for the Go-based v7.0
```
