JavaScript Operator

Operator can be used to perform any operation like - Arithmetic operation , Assignment operation ,Logical operation , Bitwise operation

Example

Assignment operator ( = )are used to assign value to a variable

/***** This is index.html file ****/

<script>

var int =4;  // Assignment operator

console.log(int);

</script>

Result

4

Example

Arithmetic operator used to perform arithmetic operation

Addition Operator ( + )

/*** This is index.html file ****/

<script>

var x = 8;

var y = 14;

var z = x+y;

console.log(z);

</script>

Result

22

Arithmetic Operator

Arithmetic Operator used to perform arithmetic operation

Operator      Example      Name

+                    x+y                Addition

-                     x-y                 Subtraction

*                    x*y                  Multiplication

/                    x/y                  Division

**                  x**y                 Exponentiation( ES2016)

%                   x%y                 Modulus

++                 x++                Increment

--                  x--                    Decrement                       

Example

Subtraction arithmetic operator

var x = 14;

var y = 2;

var z = x - y;

console.log(z);

Assignment Operator

Assignment operator use to assign value to a variable

Operator         Example         Detail

 =                      x=y                  equal to

+=                     x+=y                x=x+y

-=                      x-=y                 x=x-y

*=                     x*=y                 x=x*y

/=                     x /=y                x=x/y

%=                    x%=y               x=x % y

**=                   x**=y               x=x**y

&=                    x&=y                x=x&y

^=                    x^=y                 x=x^y

&&=                 x&&=y              x&&(x=y)

<<=                  x<<=y              x=x<<y

>>=                   x>>=y             x=x>>y    

Example

Assignment operator

var x = 5;

var y =4;

x+=y;     // Assign operator

console.log(x);

 Comparison Operator

Comparison operator used to compare value and it return true or false

Operator       Example         Description

==                   x==y                equal to

!=                    x!=y                  not equal to

===                x===y               strict equal

!==                  x!==y                strict not equal

>                      x>y                     greater than

>=                    x>=y                   greater than equal

<                       x<y                      less than
