TypeScript 6.0 bridges JavaScript, Go era

TypeScript 6.0 feels less like a feature dump and more like a migration checkpoint for the native compiler era. The upside is cleaner defaults and less config drag; the cost is that old tsconfig habits now become impossible to ignore.

• –`strict`, `module: esnext`, and `target: es2025` now match how most teams ship today, which is great for greenfield projects but a real nudge for legacy repos.
• –`types: []` and `rootDir: "."` reduce hidden ambient type noise and make builds more predictable, especially in large monorepos.
• –Deprecations around `es5`, `classic`, `outFile`, `baseUrl`, and `alwaysStrict: false` are TypeScript finally charging interest on years of config debt.
• –`--stableTypeOrdering` is the tell: 6.0 is preparing the ecosystem for a parallel, native 7.0 without letting compiler output turn chaotic. [Microsoft announcement](https://devblogs.microsoft.com/typescript/announcing-typescript-6-0/)
