- 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
