unique

unique<T>(xs, eq): IteratorObject<T>

Take the Iterable and remove all items that are duplicated. Duplications are detected by applying the eq operator.

Example

collect(unique([1, 2, 3]))
// => [1, 2, 3]

collect(unique([1, 2, 1, 2, 3]))
// => [1, 2, 3]

function* foobar() {
    yield 'foo'
    yield 'bar'
}
collect(unique(foobar()))
// => ["foo", "bar"]

collect(unique([]))
// => []
