TypeScript vs JavaScript: Which Should You Use for Web Development?
Choosing the right language for your next web project can be tough. Both JavaScript and TypeScript are popular, but which one is right for you?
What is JavaScript?
JavaScript is the language of the web. It's dynamic, flexible, and supported everywhere.
What is TypeScript?
TypeScript is a superset of JavaScript that adds static typing. It helps catch errors early and improves code maintainability.
Key Differences
- Type Safety: TypeScript provides static type checking, JavaScript does not.
- Tooling: TypeScript offers better editor support and refactoring tools.
- Learning Curve: JavaScript is easier for beginners; TypeScript requires learning types.
Example: TypeScript vs JavaScript
// JavaScript
function greet(name) {
return 'Hello, ' + name;
}
// TypeScript
type GreetProps = { name: string };
function greetTS({ name }: GreetProps): string {
return `Hello, ${name}`;
}

Conclusion
- Use JavaScript for quick prototypes or when working with legacy code
- Use TypeScript for large, maintainable, and scalable projects
