The post discusses the nuances of TypeScript support in JavaScript runtimes like Node.js, Bun, and Deno. Node.js 22.6 introduces experimental support by stripping TypeScript types and treating them as JavaScript, without type checking. Comparatively, Bun also strips types but doesn't perform type checking, while Deno offers both stripping and type checking natively. The post explores using TSC for type checking in environments lacking built-in support and evaluates tools like TS Node and TSX.
