Mastering TypeScript for React Developers

TypeScript has become essential for React development.

Essential Types for React

interface ButtonProps {
  variant: 'primary' | 'secondary' | 'outline'
  size?: 'sm' | 'md' | 'lg'
  children: React.ReactNode
}

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

Use interfaces for object shapes

Prefer union types over enums

Use type guards for runtime checks

Leverage utility types (Partial, Pick, Omit)

Avoid `any` - use `unknown` instead

TypeScript makes your React code more robust and maintainable.
