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

Example 1:: _arr1 = [1,[2,[3]]]; _arr2 = [1,[2,[3]]]; if (_arr1 isEqualTo _arr2) then {hint "Arrays match!"}
Example 2:: if (a isEqualTo b) then {hint "a is equal to b"}; if !(a isEqualTo b) then {hint "a is not equal to b"};

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

Tajin: 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 "==".

Killzone Kid: A faster, case-sensitive alternative to BIS_fnc_areEqual using isEqualTo: KK_fnc_allEqual = { private ["_arr", "_first"]; _arr = []; _first = _this select 0; for "_i" from 0 to count _this - 1 do { _arr pushBack _first; }; _arr isEqualTo _this }; // Example [[1,2],[1,2],[1,3]] call KK_fnc_allEqual; //false
