TypeScript · Junior · Question 73 of 75

Can recent Node.js versions run a `.ts` file directly?

✓Correct answer: Yes - Node can strip erasable type annotations and run the file, but it doesn't type-check
2No - Node only runs .js
3Yes, and it reports type errors like tsc

Explanation

Type stripping removes types without transformation, so features that generate code (like enum) need extra flags or a compiler.
