Modulus (%)
Modulus (%) operator returns only the remainder.
If either value is a string, an attempt is made to convert the string to a number.
For example, the following line of code
var resultOfMod = 26 % 3;
%= (Modulus Assignment)
The modulus assignment operator divides the value stored in the left variable by the right value. If value is a string, an attempt is made to convert the string to a number before performing the modulus and assignment.
