Hi, how to get an array with just common entries from two arrays?:
array1 = ["q", "w", "e", "r", "t", "y"]
array2 = ["w", "t", "z"]
I want to get:
array_common = ["w", "t"]
I don0t find an ellegant and fast way to get it. Any help?
Thanks a lot.

array_common = array1 - (array1 - array2)
=> ["w", "t"]
