JS Practice — Built-in Objects

Generics — pipe<T>

📖 Usage Example

const result = pipe(
  5,
  x => x * 2,
  x => x + 1
)  // → 11

pipe<T> threads a value through a sequence of transformations left-to-right.

Generics: Function Composition with pipe<T>

Challenge: Implement pipe<T>(...fns: ((x: T) => T)[]): (x: T) => T — a left-to-right function composer.

pipe(x => x + 1, x => x * 2)(3)  // → (3+1)*2 = 8
pipe()(42)                         // → 42
