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 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.
