The scope of global code includes two objects: the global object and the variable object. When we say that these objects are the scope of global code, we mean that the browser can access properties of these two objects only. Some of them are real properties and some are methods. The global object is the browser window object, the one you query the location of by window.location(). The variable object holds all global variables and methods. A new object is created on the entry point to the global code, and is destroyed upon exit.

The this object is the browser window object. Instead of window.location, for example, you can write this.location and get the same URL of the current page. Try it.
