(ArmA3 1.16) for multiple comparisons, we can use the example below for more accurate compare than BIS_fnc_arrayCompare or BIS_fnc_areEqual: fnc_areEqual = { private ["_b","_var1","_var2"]; _b = true; for [{_i = 1},{_i < (count _this) && _b},{_i = _i + 1}] do { _var1 = _this select (_i-1); _var2 = _this select _i; if (!(_var1 isEqualTo _var2)) then {_b = false;}; }; _b }; ["A","a","a"] call fnc_areEqual; // false ["A","a","a"] call BIS_fnc_areEqual; // true

The behavior of "var1 isEqualTo var2" is pretty much equivalent to "var1 in [var2]", plus the ability to compare arrays, and slightly better performance.

Simply put, "isEqualTo" is a binary comparison. Therefor it is very fast but only accepts 100% identical matches. In some other languages this is known as "===" instead of "==".
