Operators 161

Example

In the following example, the variable

happy is set to false. The if condition evaluates the

condition

!happy, and if the condition is true, the trace() statement sends a string to the

Output panel.

var happy:Boolean = false;

if (!happy) {

trace("don't worry, be happy"); //traces don't worry, be happy

}

The statement traces because !false equals true.
