JavaScript BOM Window Screen

The Browser Object Model (BOM) is a browser-specific convention referring to all the objects exposed by the web browser. The BOM allows JavaScript to "interact with" the browser. The object of the window represents a browser window and all its corresponding features. A window object is created automatically by the browser itself. Java Script's window.screen object contains information about the user's screen. It can also be written without the window prefix.
