The Window object is one of the top-level objects of the client-side JavaScript, and whenever you open a browser window, regardless of whether there are open pages in that window, an instance of the Window object is created automatically when you encounter a body, frameset, or FRAME element. Also, an instance of the object can be created by the window.open () method. Because the window object is a common ancestor of most other objects, you can omit a reference to the Window object when invoking the methods and properties of the Window object. For example: Window.document.write () can be simply written as: document.write (). You can omit the window's instance name when you PIDM minimises any methods and properties of the Window object in the window. For example, when you set the Status property for the current Mywin window, you can use status instead of Mywin.status. However, you must use the instance name when you call the Location property, the Close () method, or the open () method in event handling.
the Window object has the following methods:Open

Prompt
SetTimeout

SetInterval

Moveby
