dropRight() function

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

Signature:

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

Example

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

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

pipe(
 "abcde",
 dropRight(2),
 toArray,
); // ["a", "b", "c"]

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

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