The History API provides these methods:

• back()
• forward()
• go()

To go back to the previous page:

history.back()

This navigates to the previous entry in the session history. To go forward to the next page:

history.forward()

This is the same as using the browser back and forward buttons.

go() lets you move back or forward by multiple steps. For example:

history.go(-1) // equivalent to history.back()
history.go(-2) // equivalent to calling history.back() twice
history.go(1) // equivalent to history.forward()
history.go(3) // same as calling history.forward() three times

To get the number of entries in the history:

history.length
