uniq() function

Returns Iterable/AsyncIterable with duplicate values removed inside the given Iterable/AsyncIterable. Only primitive values can be compared. The order of result values is determined by the order they occur in the array.

Signature:

typescript
declare function uniq<A extends Iterable<unknown> | AsyncIterable<unknown>>(iterable: A): ReturnIterableIteratorType<A>;

Example

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

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

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

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