Hi, Im not totally sure what you are trying to answer. 

Do you want:
1. a function that returns true when passed arguments of [A,B] and [A,B] but false when passed [A,B] and [A,B,C]? (array compare); or
2. a function that when passed [A,B] and [A,C,D] will return [B, C, D]? (array diff); or
3. Something different? From the above?

With for and while loops, one can make a function that does just about anything with arrays in Xano, but need to understand the inputs and outputs to recommend either a built-in or how you could approach with a custom function.

First option
Do you have any solution for array compare

The built-in array_diff function in Xano makes this relatively easy to do. You can ask which elements are in the first array but not in the second, and then ask the question in reverse to get the true/false you are looking for. I made a short video showing how to do this: https://www.loom.com/share/b645e1fb9a21420897c0acd75753e615
