To clarify AgentRevolution's note, he is saying that the [[in]] command and [[isEqualTo]] use the same comparison algorithm. If we were able to look at the code for the [[in]] command, I bet you would find [[isEqualTo]] in there also.

Description

Description:
Performs strict comparison between var1 and var2 and returns true if equal otherwise false.

Some differences between == and isEqualTo:
  • Performs case sensitive comparison on Strings
  • Doesn't throw error when comparing different types, i.e. ("eleven" isEqualTo 11)
  • Can compare Arrays and Booleans

(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 "==".
