Benchmarks on large real-world codebases show dramatic improvements — Visual Studio Code's build time dropped from 125.7 seconds to 10.6 seconds (11.9x speedup), with similar gains for Sentry, Bluesky, Playwright, and others. Memory usage also decreased. The release is considered production-ready, having been tested with Slack, Canva, and Microsoft internal projects. New features include type checker parallelization, project reference builder parallelization, improved watch mode, and updated defaults (strict: true, module: ESNext). The speed improvement applies to compilation and editor tooling, not runtime performance of the output JavaScript. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How much faster is TypeScript 7 compared to TypeScript 6? TypeScript 7 is roughly 8x to 12x faster on full builds because its compiler (TSC) was rewritten natively in Go instead of TypeScript, adding shared-memory multithreading and native code speed. Visual Studio Code's compilation time dropped from 125.7 seconds to 10.6 seconds, an 11.9x speedup, while memory usage fell from 5.2GB to 4.2GB. _Track compiler-level upgrades like this on daily.dev before rolling out a TypeScript 7 migration._ ### Does TypeScript 7 make my compiled JavaScript run faster at runtime? No, the speedup in TypeScript 7 applies only to compilation and tooling, not runtime JavaScript performance. Since TypeScript still transpiles to JavaScript, the 8x-12x gains improve editor load times, autocomplete, diagnostics, and watch mode feedback loops rather than frames per second or execution speed in the browser. _daily.dev helps developers separate real runtime gains from tooling speedups when evaluating releases._ ### Can I run TypeScript 7 alongside TypeScript 6 in the same project? Yes, TypeScript 7 is designed to run side by side with TypeScript 6, and it is considered production-ready after testing with projects including Slack, Vanta, Microsoft, Loop, and Canva. This lets teams migrate large codebases incrementally rather than switching all at once. _Developers planning gradual migrations follow release compatibility details like this via daily.dev._ ## Similar posts on daily.dev - [TypeScript 7.0 Rewrote Its Compiler in Go.
