Description:: Returns true only if both conditions are true. In case of the alternative syntax, lazy evaluation is used - if left operand is false, evaluation of the right side is ignored.
Alias:: a and b
Groups:: Variables Math

Syntax:: boolean && code
Parameters:: boolean: Boolean - test condition or variable
: code: Code - code that once executed returns a Boolean. The code is not evaluated if boolean is false.
Return Value:: Boolean

Example 1:: private _allEnemiesKilled = true; if (alive player && _allEnemiesKilled) then { hint "you win !"; };
Example 2:: if ((count _array > 0) && { (_array select 0) == player }) then // an error would be thrown without lazy evaluation { hint "It works!"; };
Example 3:: if ((alive player) && { player setDamage 0.5; true }) then // valid AS LONG AS the code block returns a Boolean { hint "It works!"; };
