void The void operator evaluates an expression without returning a value. Although the use of brackets after it is optional, it is good style to use them. The following example creates a hyperlink on the word "green" which, when clicked, changes the background color to light green: Code: Sam turned <a href="java script:void(document.bgColor='lightgreen')">green</a>.
