JavaScript Assignment Operators (Configuration Operators) are the markers used to configure to variables in the JavaScript language.

The most common operator is the single equals sign (=), which assigns a right value to the variable on the left.

Operator Name Example Meaning

Assignment x = y requires that x is equal to y.

+ = Addition Assignment x + = y is equivalent to: x = x + y

－ = Subtraction Assignment x － = y is equivalent to: x = x － y.

☆ = Multiplication Assignment x ☆ = y is equivalent to: x = x ☆ y

/ = Division Assignment x / = y is equivalent to: x = x / y.

% = Remainder Assignment x% = y is equivalent to: x = x% y (rest from division).

Compound Assignment Operators

In addition to =, JavaScript also provides abbreviated configuration operators (such as + =, － =, etc.) that combine mathematical or bitwise operations (bitwise) with the configuration, which allows more concise and easier to read code.

Example of use

Suppose the variable x has a default value of 10:

JavaScript

Let x = 10;

Let y = 5;

/ / Use of + = (Addition Assignment)

x + = y; / / is equivalent to x = x + y; (x will be 15)

/ / Usage - = (Subtraction Assignment)

x - = 3; / / is equivalent to x = x - 3; (x will be 12)

/ / Usage * = (Multiplication Assignment)

x * = 2; / / is equivalent to x = x * 2; (x will be 24)

Note: There are also other configuration operators for bitwise operations (Bitwise Assignment Operators), such as < < =, > > =, $& = $, ️ =, and =.
