Assignment Operator (=) (JavaScript)

Assigns a value to a variable.

result = expression


Any variable.


Any numeric expression.

As the = operator behaves like other operators, expressions using it have a value in addition to assigning that value into variable. This means that you can chain assignment operators as follows:

j = k = l = 0;

j, k, and l equal zero after the example statement is executed.
