For script comparison we need to detect whether scripts are running in advance, then compose both into string:
It is recommended to use isEqualTo for all types comparison, which is more functional and as fast as operator.
For multiple comparisons:
And we can use such workaround instead of using BIS_fnc_arrayCompare or BIS_fnc_areEqual
