How to use Comparison Operators in Java Script:

Equal (==) return true if operands are equal

Not equal (!=)  if the values of operands are not equal return true  

Strict equal (===) not only check values but also type if both equal return true else false.

Strict not equal (!==) return true if type or value of operands are not  equal.

Greater than (>) if left operand is greater than right return true;

Greater than or equal (>=) Returns true if the left operand is greater than or equal to the right operand.  

Less than (<) return true if left operand less than right operand.

Less than or equal (<=) return true if left operand is less or equal to right operand.
