Chapter 18. navigator > Description

Description

The navigator object describes to JavaScript the client browser's details. This includes such things as the operating system, the computer it runs on, plug-ins the browser has available, and what kind of documents the browser can accept. However, the specifics of the navigator object can vary significantly between browsers. It is important to note that in Netscape 4 and probably previous versions the navigator object was a global object with one instance for all browsers. In Internet Explorer 4+ and Netscape 6 each window has its own navigator object.

In Microsoft Internet Explorer, as of version 4, the window.clientInformation property refers to the same object as the navigator property.
