2.6 JS Assignment

Assignment operators assign values to JavaScript variables.

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 = 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

The **= operator is a part of ECMAScript 2016.

Assignment Examples

The = assignment operator assigns a value to a variable.

Example 1: JavaScript assignment part 1

var x = 10;

The += assignment operator adds a value to a variable.

Example 2: JavaScript assignment part 2

var x = 10;
x += 5;

The -= assignment operator subtracts a value from a variable.

Example 3: JavaScript assignment part 3

var x = 10;
x -= 5;

The *= assignment operator multiplies a variable.

Example 4: JavaScript assignment part 4

var x = 10;
x *= 5;

The /= assignment divides a variable.

Example 5: JavaScript assignment part 5

var x = 10;
x /= 5;

The %= assignment operator assigns a remainder to a variable.

Example 6 JavaScript assignment part 6

var x = 10;
x %= 5;
