Finding what is common to two arrays

Question

Is there a way to compare two arrays and show what is common to both of them?

array1 = [\"pig\", \"dog\", \"cat\"]
array2 = [\"dog\", \"cat\", \"pig\", \"hor         


        

Answer 1

You can intersect the arrays using &:

array1 & array2

This will return ["pig", "dog", "cat"].
