TypeScript Best Practices

Level up your TypeScript skills with these essential patterns.

Use Strict Mode

Always enable strict mode in tsconfig.json:

{
  "compilerOptions": {
    "strict": true
  }
}

Prefer Type Inference

Let TypeScript infer types when possible:

const name = 'John'; // inferred as string

Use Utility Types

Take advantage of built-in utility types like Partial, Required, Pick, and Omit.

Conclusion

Following these patterns will make your TypeScript code more robust and maintainable.
