Understanding TypeScript's Advanced Types

Advanced TypeScript Types

TypeScript's type system is one of its most powerful features, offering advanced capabilities for type safety.

Mapped Types

type Readonly = {
  readonly [P in keyof T]: T[P];
}

Conditional Types

type ExtractType = T extends string 
  ? 'string' 
  : T extends number 
    ? 'number' 
    : 'other';

These advanced types help create more maintainable and type-safe code.
