The TypeScript 7.0 prophecy is fulfilled

TypeScript 7.0 beta has been released, featuring a full port of the TypeScript compiler from TypeScript/JavaScript to Go. The new native compiler is roughly 10x faster than TypeScript 6.0, with parallel parsing, type-checking, and emitting. Install via `npm install -D @typescript/native-preview@beta` and run `tsgo`. Breaking changes include removal of deprecated options like `target: es5`, `moduleResolution: node`, AMD/UMD/SystemJS, and `baseUrl`. The programmatic API is coming in 7.1. A stable release is expected within two months, and companies like Bloomberg, Vercel, and VoidZero are already using it in production. The newsletter also covers Rspack 2.0, Vue 2026 state, WSL9x running Linux inside Windows 9x, and a JavaScript `this` context bug with setTimeout.
