Find if variable is divisible by 2

Question

How do I figure out if a variable is divisible by 2? Furthermore I need do a function if it is and do a different function if it is not.

Answer 1

Please write the following code in your console:

var isEven = function(deep) {

  if (deep % 2 === 0) {
        return true;  
    }
    else {
        return false;    
    }
};
isEven(44);

Please Note: It will return true, if the entered number is even otherwise false.
