JavaScript gives you many ways to access and change the current URL that is displayed in the visitor’s browser. All these techniques use the Location object, which is itself a property of the Window object. You can create a new Location object that contains the current URL as follows:

var currentURL = window.location;

In this tutorial, you explore all the properties and methods of the Location object. You learn:

• How to read all the different parts of a URL
• How to send the visitor to another page by changing the URL, and
• How to automatically reload or refresh the page.
