window

window object represents the global window or browser environment in which your code is running. It serves as the top-level object, and many global properties, functions, and methods are attached to it. window provides access to various browser-related features and allows you to interact with the browser, manipulate the webpage's content, handle events, and more. It's a fundamental part of client-side web development and is used to control and manage the browser window and its interactions with the web page.

window.open(): Opens a new browser window or tab.
