 JAVASCRIPT OPERATOR:
ARITHMATIC OPERATOR
ASSIGNMENT OPERATOR
COMPARISION OPERTOR
LOGICAL OPERATOR
CONDITIONAL OPERATOR
ARITHMATIC OPERATOR:
 Arithmetic operators are used to perform arithmetic between variables
and/or values.
 Given that y=5, the table below explains the arithmetic operators:
Operator 
Description 
Example 
Result 
+ 
Addition 
x=y+2 
x=7 
 
Subtraction 
x=y2 
x=3 
* 
Multiplication 
x=y*2 
x=10 
/ 
Division 
x=y/2 
x=2.5 
% 
Modulus (division remainder) 
x=y%2 
x=1 
++ 
Increment 
x=++y 
x=6 
 
Decrement 
x=y 
x=4 
ASSIGNMENT OPERATOR:
 Assignment operators are used to assign values to JavaScript variables.
 Given that x=10 and y=5, the table below explains the assignment operators:
Operator 
Example 
Same As 
Result 
= 
x=y 

x=5 
+= 
x+=y 
x=x+y 
x=15 
= 
x=y 
x=xy 
x=5 
*= 
x*=y 
x=x*y 
x=50 
/= 
x/=y 
x=x/y 
x=2 
%= 
x%=y 
x=x%y 
x=0 
COMPARISION OPERATOR:
 Comparison operators are used in logical statements to determine equality or difference between variables or values.
 Given that x=5, the table below explains the comparison operators:
Operator 
Description 
Example 
== 
is equal to 
x==8 is false 
=== 
is exactly equal to (value and type) 
x===5 is true 
!= 
is not equal 
x!=8 is true 
> 
is greater than 
x>8 is false 
< 
is less than 
x<8 is true 
>= 
is greater than or equal to 
x>=8 is false 
<= 
is less than or equal to 
x<=8 is true 
How Can it be Used
 Comparison operators can be used in conditional statements to compare values and take action depending on the result:
For Example:
If (age<18)
document.write("Too young");
LOGICAL OPERATOR:
 Logical operators are used to determine the logic between variables or values.
 Given that x=6 and y=3, the table below explains the logical operators:
Operator 
Description 
Example 
&& 
and 
(x < 10 && y > 1) is true 
 
or 
(x==5  y==5) is false 
! 
not 
!(x==y) is true 
CONDITIONAL OPERATORS:
 JavaScript also contains a conditional operator that assigns a value to a variable based on some condition.
Syntax:
<Variable name> = <condition>? value1: value2
Example:
x = (y == 5)? “x is true”:”x is false”
 Here if value of y is 5 then value of x = “x is true”
 If value of y is not 5 then value of = “x is false”
