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 "==". | Simply put, "isEqualTo" is a binary comparison. Therefor it is very fast but only accepts '''100%''' identical matches.

Description
- Description:
- Performs strict comparison between var1 and var2 and returns true if equal, otherwise false. Strict means that it would check that both arguments are of the same data type and then compare the values.
Some differences between isEqualTo and ==:- It performs case sensitive comparison on Strings
- It doesn't throw error when comparing different types, i.e. ("eleven" isEqualTo 11)
- It can compare Arrays, Scripts and Booleans (alive player isEqualTo true)
- It can compare non-existent game objects (grpNull isEqualTo grpNull)
- It can compare Namespaces (As of Arma 3 v1.47)
- It is slightly faster than ==, especially when comparing Strings
- Groups:
- Uncategorised
Syntax
Examples
- 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"};

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