Difference returns a slice of values that are only present in one of the input slices [1, 2, 2, 4, 6] & [2, 4, 5] >> [1, 5, 6] [1, 1, 3, 4, 5, 6] >> [1, 3, 4, 5, 6].

Distinct returns the unique vals of a slice [1, 1, 2, 3] >> [1, 2, 3].

export slice from list by field.

generate IMEI.

Intersect returns a slice of values that are present in all of the input slices [1, 1, 3, 4, 5, 6] & [2, 3, 6] >> [3, 6] [1, 1, 3, 4, 5, 6] >> [1, 3, 4, 5, 6].
