The void operator is used to evaluate an expression without returning a value. It has the syntax:
void expression
where expression is the expression to evaluate. In JavaScript, void is used to evaluate a JavaScript expression in a hypertext link without causing the result to appear in the browser's address bar. There are few, if any, such applications for void in ActionScript; it is included for the sake of compatibility with ECMA-262.
