intersection(
collections: unknown[][] = [],
by?: (val: unknown) => unknown
): unknown[]Parameters

Returns
A new array containing the unique intersecting values.
Examples
const setA = [1, 2];
const setB = [2, 3];
intersection([setA, setB]) //=> [2]
const arrays = [
[1, 2, 3],
[2, 1, 5],
[3, 1],
];
intersection([...arrays]) //=> [1]
intersection(
[
[2.1, 1.2],
[2.3, 3.4],
],
Math.floor
) //=> [2.1]
