In JavaScript, the window object represents the browser window or frame in which the current web page is displayed. It provides properties and methods for controlling the browser window or frame, as well as accessing the document object and other objects associated with the current web page.
Here are some examples of using the window object in JavaScript:
Accessing the current URL:
console.log(window.location.href);
Opening a new window:
The window Attributes parameter is important as you display windows because it lets you customize the look of the window you are opening. The window Attributes parameter is optional; not including it gives you a window identical to the current one with respect to attributes.
