| Feature | TypeScript | JavaScript |
|---|---|---|
| Typing | Static, compile-time types | Dynamic, runtime types |
| Error Detection | Catch errors before runtime | Errors at runtime |
| Learning Curve | Steeper | Gentle |
| Tooling | Requires compiler/build step | Native in browser |
| Community | Growing rapidly | Massive and mature |
| Use Cases | Large codebases, strict contracts | Small projects, scripts |
TypeScript adds type safety and better tooling to JavaScript at the cost of complexity. For large apps and teams, TypeScript is recommended. For small scripts and prototyping, JavaScript is simpler.
