JS Practice — Built-in Objects

Advanced — curry

📖 Usage Example

const add = curry((a: number, b: number) => a + b)
add(1)(2)    // → 3
add(1, 2)   // → 3

curry transforms a multi-argument function so arguments can be applied one at a time.

Advanced: Generic curry

Challenge: Implement curry<A, B, C>(fn: (a: A, b: B) => C): (a: A) => (b: B) => C — a curried form of a two-argument function.

const add = curry((a: number, b: number) => a + b)
add(3)(4)  // → 7
