1. What is TypeScript?
TypeScript is a superset of JavaScript that adds static typing to the language. It was created by Microsoft to improve the development process by offering type-checking at compile-time.
2. Key Differences Between JavaScript and TypeScript
- Static vs. Dynamic Typing: TypeScript requires you to define types for variables, while JavaScript does not.
- Compilation: TypeScript needs to be compiled into JavaScript before running, while JavaScript runs directly in the browser.
- Tooling and IDE Support: TypeScript offers better tooling support with features like autocompletion and error checking.
3. When Should You Use TypeScript?
TypeScript is beneficial in large projects where maintaining and scaling code is essential. It’s particularly useful for teams working on complex applications as it reduces runtime errors and improves code maintainability.
4. Conclusion
While JavaScript is still the most widely used language for web development, TypeScript offers advantages for large-scale projects and can make JavaScript development more efficient and error-free.
