TypeScript Best Practices in 2024

TypeScript helps you write more reliable code. Here are the best practices to follow.

Strict Mode

Always enable strict mode in your tsconfig.json:

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

Type Inference

Let TypeScript infer types when possible:

const user = { name: 'John', age: 30 } // Type is inferred

Generics

Use generics to write reusable, type-safe code:

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

Utility Types

Leverage utility types like Partial, Pick, and Omit.

Conclusion

Following these practices will help you write better TypeScript code.
