Type Stripping with Zero Dependencies

- TypeScript transforms into JavaScript through 'type stripping', removing TypeScript syntax.
- Browsers and older Node.js versions require bundlers for type stripping, but recent Node.js versions support it natively.
- Node.js performs type stripping before passing code to V8, replacing TypeScript syntax with blank space.
- The `toString()` method on functions can reveal the stripped JavaScript source code, as demonstrated with a `createProfile` function example.
- Wunphile, a static site generator, uses this Node.js feature to allow TypeScript in components without bundlers or external dependencies.
- Limitations include the inability to strip TypeScript from arbitrary strings or code not directly read from TypeScript files by Node.js.
