🔷TypeScript
- ✓Catches type errors at compile time, not in production
- ✓Superb editor autocomplete and refactoring tools
- ✓Self-documenting code that scales with team size
- ✓Compiles down to plain JavaScript anywhere it runs
🟨JavaScript
- ✓Zero build step — run it directly in any browser
- ✓Lower barrier to entry for beginners
- ✓Faster prototyping with no type ceremony
- ✓Universal — 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.
Frequently asked
Is TypeScript hard to learn?+
If you know JavaScript, the basics take a day; advanced types take longer but are optional.
Does TypeScript slow down development?+
Initially it adds typing work, but it saves far more time by preventing bugs at scale.
Can I mix both in one project?+
Yes — TypeScript allows gradual adoption, file by file, alongside JavaScript.
