  • βœ“Catches type errors at compile time, not in production
  • βœ“Superb editor autocomplete and refactoring tools
  • βœ“Self-documenting code that scales with team size
  • βœ“Compiles down to plain JavaScript anywhere it runs
🟨JavaScript
  • βœ“Zero build step β€” run it directly in any browser
  • βœ“Lower barrier to entry for beginners
  • βœ“Faster prototyping with no type ceremony
  • βœ“Universal β€” every JS engine runs it natively

Verdict

Pick TypeScript for any project beyond a small script or larger teams. Pick plain JavaScript for quick prototypes, learning, or tiny scripts.
