The history list is represented in JavaScript by the window.history object. This object lets you deal with the history list but not with its exact data. That is, the URLs maintained in that list cannot be extracted or otherwise modified by a script. The only property of this object is its length. Its methods enable you to load the list's entries but not to manipulate the URL explicitly. Since the history object is a property of the topmost window object, you have the option to refer to it as window.history or simply history.

You can access the number of entries in the history list via the history.length property. It works exactly like the strings' and arrays' length property. You can use this property to find how many pages the user has visited lately:

if (history.length) > 10
  alert("You've already accessed " + history length + " Web pages this session");
  alert("You've only accessed " + history.length + " Web pages this session");
