Static Typing vs Dynamic Flexibility
TypeScript catches bugs at compile time, improves IDE support, and is essential for large-scale projects. JavaScript is simpler, has no build step, and is faster for prototyping and small scripts.
Microsoft's typed superset of JavaScript that compiles to plain JS — adds static types, interfaces, and better tooling
The dynamic scripting language of the web — runs natively in every browser and powers Node.js, React, and most web frameworks
| Feature | TypeScript | JavaScript |
|---|---|---|
| Type system | Static typing (compile-time checks) | Dynamic typing (runtime only) |
| IDE support | Excellent (autocomplete, refactoring) | Good (but less precise) |
| Build step | Required (tsc compiler) | None (runs natively) |
| Learning curve | Moderate (need to learn types) | Lower (more forgiving) |
| Ecosystem | Full JS ecosystem + @types packages | Largest package ecosystem (npm) |
| Error catching | Compile-time + runtime | Runtime only |
| Refactoring | Safe (type-checked) | Risky (no type safety) |
| Adoption | Growing rapidly (most new projects) | Universal (runs everywhere) |

Choose TypeScript for large codebases, team projects, and catching bugs early. Choose JavaScript for quick prototyping, small scripts, and when you want zero build overhead.
