The Debugger Object ($)
The $ Object (Debugger Object) provides properties and methods you can use to debug your JavaScript code. For example, you can call its methods to set or clear breakpoints programmatically, or to change the language flavor of the script currently executing. It also provides properties that hold information about the version of the host platform's operating system.
NOTE: The $ object is not a standard JavaScript object.
