TypeScript Best Practices

TypeScript Fundamentals

TypeScript adds static typing to JavaScript, making your code more reliable and maintainable. Here are the best practices to follow.

Type Definitions

Always define explicit types for better code clarity:

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

function createUser(userData: Partial): User {
  return {
    id: Date.now(),
    name: userData.name || '',
    email: userData.email || '',
    isActive: userData.isActive ?? true
  };
}

Conclusion

TypeScript is a powerful tool that can significantly improve your JavaScript development experience when used correctly.
