What are JavaScript Operators and its Types?

Operator

Description

Example

+

Adds two operands

10 + 20 = 30

–

Subtracts the second operand from the first

30 – 20 = 10

/

Divide the numerator by the denominator

20/10 = 2

*

Multiply two operands

5 * 5 = 25

%

Outputs the remainder of an integer division

20 % 10 = 0

++

Increases an integer value by one

var a=20; a++; Now a = 21

—

Decreases an integer value by one

var a=20; a–; Now a = 19

Operator

Description

Example

==

Checks if two operands are equal or not. If yes, then the condition becomes true.

20==30 = false

===

Finds the identical (equal and of the same type)

10==20 = false

!=

Checks if two operands are equal or not. If the values are not equal, then the condition becomes true

20!=30 = true

!==

It implies that two values are not Identical

20!==20 = false

>

Checks if the value of the left operand is greater than the value of the right operand

30>10 = true

>=

Checks if the value of the left operand is greater than or equal to the value of the right operand

20>=10 = true

<

This Checks if the value of the left operand is less than the value of the right operand

20<10 = false

<=

Checks if the value of the left operand is less than or equal to the value of the right operand

30<=10 = false

Operator

Description

Example

&

Boolean AND operation on each bit of its integer arguments

(10==20 & 20==33) = false

|

It performs a Boolean OR operation on each bit of its integer arguments

(10==20 | 20==33) = false

^

This operator performs Bitwise XOR operation

(10==20 ^ 20==33) = false

~

It is a unary operator and operates by reversing all the bits in the operand

(~10) = -10

<<

Moves all the bits in its first operand to the left by the number of places specified in the second operand.

(10<<2) = 40

>>

The left operand’s value is moved right by the number of bits specified by the right operand.

(10>>2) = 2

>>>

This operator is just like the >> operator, except that the bits shifted in on the left are always zero.

(10>>>2) = 2

Operator

Description

Example

&&

(10==20 && 20==33) = false

||

(10==20 || 20==33) = false

!

!(10==20) = true

Operator

Description

Example

=

20+10 = 30

+=

var a=20; a+=10; Now a = 30

-=

var a=30; a-=10; Now a = 20

*=

var a=10; a*=20; Now a = 200

/=

var a=10; a/=2; Now a = 5

%=

var a=10; a%=2; Now a = 0
