Operators

JavaScript language supports following type of operators.

1. Arithmetic Operators.
2. Comparision Operators.
3. Logical  Operators.
4. Assignment Operators.

Arithmetic Operators

Assume variable A holds 10 and variable B holds 20 then

Operator	Description	Example
+	Adds two operands	A + B will give 30
-	Subtracts second operand from the first	A - B will give -10
*	Multiply both operands	A * B will give 200
/	Divide numerator by denumerator	B / A will give 2
%	Modulus Operator and remainder of after an integer division	B % A will give 0
++	Increment operator, increases integer value by one	A++ will give 11
--	Decrement operator, decreases integer value by one	A-- will give 9

Comparison Operators

Given that x=5, the table below explains the comparison operators:

Operator	Description	Comparing	Returns
==	Is Equal to	x==8	false
		x==5	true
===	Is Exactly equal to (value and type)	x==="5"	false
		x===5	true
!=	Is Not Equal	x!=8	true
!==	Is Not Equal (neither value nor type)	x!=="5"	true
		x!==5	false
>	Is Greater than	x>8	flase
<	Is Less than	x<8	true
>=	Is Greater than or Equal to	x>=8	false
<=	Is Less than or Equal to	x<=8	true
