TypeScript 7.0 RC brings Go-based codebase and 10x faster builds (opens in new tab)

Release Candidate features a new Go-based codebase, delivering up to 10 times faster performance than version 6.0. Parallel processing is now supported for parsing, type-checking, and project building via new configuration flags. The updated --watch mode uses a Go-based file watcher derived from Parcel for greater efficiency. The release remains compatible with TypeScript 6.0 but strictly enforces all previous deprecations as hard errors. |
