drop

drop() function

Returns all but the first length elements of the given iterable.

Signature:

declare function drop<A>(length: number, iterable: Iterable<A>): IterableIterator<A>;

declare function drop<A>(length: number, iterable: AsyncIterable<A>): AsyncIterableIterator<A>;

declare function drop<A extends Iterable<unknown> | AsyncIterable<unknown>>(length: number): (iterable: A) => ReturnIterableIteratorType<A>;

Example

const iter = drop(2, [1, 2, 3, 4]);
iter.next() // {done:false, value: 3}
iter.next() // {done:false, value: 4}
iter.next() // {done:true, value: undefined}

// with pipe
pipe(
 [1, 2, 3, 4],
 drop(2),
 toArray,
); // [3, 4]

await pipe(
 Promise.resolve([1, 2, 3, 4]),
 drop(2),
 toArray,
); // [3, 4]

// with toAsync
await pipe(
 [Promise.resolve(1), Promise.resolve(2), Promise.resolve(3), Promise.resolve(4)],
 toAsync,
 drop(2),
 toArray,
); // [3, 4]
