TypeScript Best Practices

TypeScript adds a layer of type safety to JavaScript. Here are the best practices.

Type Safety

Always define explicit types for function parameters and return values.

function greet(name: string): string {
  return `Hello, ${name}!`;
}

Interfaces Over Types

Use interfaces for object shapes when possible.

interface User {
  id: number;
  name: string;
  email: string;
}

Generics

Generics provide flexibility while maintaining type safety.

function identity<T>(arg: T): T {
  return arg;
}

Strict Mode

Enable strict mode in tsconfig.json for maximum safety.

Conclusion

TypeScript helps catch bugs early and improves code quality.
