Muhammad Usman| Feature | JavaScript | TypeScript |
|---|---|---|
| Type System | Dynamic (loosely typed) | Static (strongly typed with optional types) |
| Compilation | Interpreted by browsers | Compiled to JavaScript |
| Error Checking | Errors appear at runtime | Errors detected at compile time |
| Code Maintainability | Can be harder to maintain in large projects | Easier maintenance with type safety |
| Object-Oriented Features | Supports OOP but lacks some features | Has interfaces, generics, and better OOP support |
| ES6+ Features | Supported | Supports all JavaScript features + additional ones |
| Browser Support | Directly supported by browsers | Needs to be compiled to JavaScript |
| Learning Curve | Easier for beginners | Requires learning types and compilation process |
| Tooling & IDE Support | Basic support | Better autocompletion, refactoring, and debugging in IDEs |
When to Use What?
- Use JavaScript for quick scripts, small projects, or when working directly with the browser.
- Use TypeScript for large-scale applications, better maintainability, and type safety.
