JS Operators

JavaScript operators are symbols that are used to perform operations on operands. For example:

Here, + is the arithmetic operator and = is the assignment operator.

There are following types of operators in JavaScript.

1. Arithmetic Operators

2. Comparison (Relational) Operators

3. Bitwise Operators

4. Logical Operators

5. Assignment Operators

6. Special Operators

JavaScript Arithmetic Operators

Arithmetic operators are used to perform arithmetic operations on the operands. The following operators are known as JavaScript arithmetic operators.

Operator	Description	Example
+	Addition	10+20 = 30
-	Subtraction	50-40 = 10
*	Multiplication	50*4 = 200
-	Division	50/2 = 25
%	Modulus	20%10 = 0
++	Increment	var a=100 ; a++; Now a = 101
--	Decrement	var a=100 ; a--; Now a = 99

JavaScript Comparison Operators

The JavaScript comparison operator compares the two operands. The comparison operators are as follows:

Operator	Description	Example
==	is equal to	10===20 = false
===	Identical (equal and of same type)	10==20 = false
!=	Not equal to	10!=20 = true
-	Not identical	20!==20 = false
>	Greater than	20 > 5 = true
>=	Greater than or equal to	20 > = 20 = true
<	Less than	20 < 5 = false
<=	Less than or equal to	20 <= 20 = true

JavaScript Bitwise Operators

The bitwise operators perform bitwise operations on operands. The bitwise operators are as follows:

Operator	Description	Example
&	Bitwise AND	(10==20 & 20==33) = false
!	Bitwise OR	(10==20 | 20==33) = false
^	Bitwise XOR	(10==20 ^ 20==33) = false
~	Bitwise NOT	(~10) = -10
<<	Bitwise left shift	(10<<2) = 40
>>	Bitwise Right shift	(10>>2) = 2
>>>	Bitwise Right shift with zero	(10>>>2) = 2

JavaScript logical Operators

The following operators are known as JavaScript logical operators.

Operator	Description	Example
&&	Logical AND	(10==20 && 20==33) = false
||	Logical OR	(10==20 || 20==33) = false
!	Logical NOT	!(10==20) = true

JavaScript Assignment Operators

The following operators are known as JavaScript assignment operators.

Operator	Description	Example
=	Assign	10+15=25
+=	Add and assign	var a=10; a+=20; Now a = 30
-=	Subtract and assign	var a=20; a-=10; Now a = 10
*=	Multiply and assign	var a=10; a*=20; Now a = 200
/=	Divide and assign	var a=10; a/=2; Now a = 5

Now that you know operators in javascript, let's learn type conversion in javascript
