Simple array comparison?

[jo spanner 13]

Hey, I have a quick question:

Is there a way to check of all elements of an array are inside another array?

I can imagine a way of writing code for this, but I wonder if there is some built-in function that might be quicker?

 

Something to the effect of:

array1 = [1,2,3];
array2 = [5,1,6,2,7,3];

array1 in array2; //evaluates to true?

Just messing around here. There are likely cases where this will not work, but it seems to work for simple arrays like this. I'm sure there is a much more elegant solution.

Code:

_a1 = [1,2,3];
_a2 = [1,2,3,4,5];

_compare = _a1 arrayIntersect _a2;
_bool = _compare isEqualTo _a1;

hint str _bool;

Result:
0.0092 ms
