TypeScript enhances JavaScript by adding static typing and advanced features for large-scale applications. It offers:
- Static Typing: TypeScript enforces type checks during development, reducing errors and enhancing code quality.
- Type Annotations: Clear documentation through type annotations, aiding code readability and maintenance.
- Compile-Time Checks: Errors are caught during compilation, reducing runtime surprises.
- Advanced Tooling: Enhanced code intelligence, navigation, and autocompletion in IDEs.
- Interfaces & Generics: Structured type definitions and reusable code patterns.
- ES6+ Compatibility: TypeScript supports the latest JavaScript features.
- Strict Mode: Allows you to define stricter type checking rules.
JavaScript, on the other hand, is a dynamic scripting language. It offers:
- Dynamic Typing: Variables can change types during runtime.
- Simplicity: Faster development due to looser syntax and fewer constraints.
- Ubiquity: Widely supported by browsers and server-side platforms.
- Learning Curve: Easy to learn and quick to get started.
- Flexibility: Dynamic nature allows for more rapid prototyping.
Both languages have their strengths. TypeScript is preferable for complex projects where strong typing and
