Here, in this guide, you will learn about JavaScript assignment operators and their usages. In the previous JavaScript tutorial, we have covered JavaScript functions to perform specific task.

JavaScript Assignment Operators

Assignment operators in JavaScript is used to assign the value to the JavaScript variable.

Operator	Example	Same As
=	x=y	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 >>= y
>>>=	x>>>=y	x >>>= y
&=	x &= y	x = x&y
^=	x^=y	x = x ^ y
|=	x |=y	x = x | y

JavaScript Assignment Operators Examples

Here we will see various examples of assignment operators.
