All the tags, elements with attributes in HTML are part of the document.

    * window
    It represents a browser window or frame that displays the contents of the webpage.
    It is the very first object that is loaded in the browser.
    It is the object of the browser
    Global objects, functions, and variables of JavaScript are members of the window object.
    We can access the window from the window only. i.e. window.window
    The window is part of BOM, not DOM.
    Properties of the window object cannot be accessed by the document object.
    syntax:

            window.confrim;   


           It is used to display a modal dialog with an optional message and two buttons 
           i.e. OK and Cancel. It returns true if the user clicks “OK”, and false otherwise.
