Creating Windows
The open method can be used to create any primary or secondary window.
window.open("web.html", "newWin", "resizeable,menubar,toolbar");
This creates a window that is resizable, contains a menu bar, and has a toolbar.
The "web.html" is the file that will open in the newly created window.
"newWin" represents the name of the window object.
Other features include outerHeight, outerWidth, innerHeight, innerWidth, alwaysRaised, alwaysLowered, location, screenY, and screenX.
The features are specified in the parameters of the open function.

Windows in Action
The window object is one level higher than the document object in the JavaScript object hierarchy.
The window object can manipulate the current window as well as create new window instances.
If window B is created by window A, window B is considered a child of window A.
