/* 
JavaScript includes operators as in other languages. An operator performs
some operation on single or multiple operands (data value) and produces a
result. For example 1 + 2, where + sign is an operator and 1 is left operand
and 2 is right operand. + operator adds two numeric values and produces a
result which is 3 in this case.
