#Compiler

The swc-project Rust compiler released v1.15.26 with bug fixes, performance improvements, and continued integration across the Node.js and bundler ecosystem.

TypeScript 6.0 is out — and the Microsoft team is clear: it's a bridge release. The real story is what comes next: TypeScript 7, written in Go and already available as a preview, promises a 10x speedup.

Microsoft ships TypeScript 6.0 as the final release built on the original JavaScript codebase. DOM type updates, improved inference, subpath imports, and a migration flag set the stage for the native Go-based TypeScript 7.0.

Microsoft's decision to port the TypeScript compiler and language service to Go isn't just a tech demo — early benchmarks show the VS Code codebase compiling in 7.5 seconds versus 77.8 seconds. Here's what the native era means for your build pipeline and editor performance.
