uniq() function

返回移除给定 Iterable/AsyncIterable 内重复值的 Iterable/AsyncIterable。只能比较原始值。结果值的顺序由它们在数组中出现的顺序决定。

Signature:

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

Example

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]
