JavaScript History Object

The History Object

The history object contains the URLs visited by the user.

The history object is part of the window object and can be written without the window prefix.

The History object allows manipulation of the browser session history, that is the pages visited in the tab or frame that the current page is loaded in.

To protect the privacy of the users, there are limitations to how JavaScript can access this object.
