The history object records the pages (URLs) that the user has browsed, and enables the browser to move forward and backward with similar navigation capabilities.

Note: starting from the moment the window is opened, each browser window, every tab, and even each frame has its own history object associated with a particular window object.

Grammar:

Window.history. [Properties | method]

Note:window can be omitted.
