intersect()

The intersect method removes any values from the original collection that are not present in the given array or collection. The resulting collection will preserve the original collection's keys:

const collection = collect([1, 2, 3, 4, 5]);

intersect = collection.intersect([1, 2, 3, 9]);

intersect.all();

// [1, 2, 3]
