History: back() method
The back() method of the History interface causes
the browser to move back one page in the session history.
It has the same
effect as calling history.go(-1). If there is no previous
page, this method call does nothing.
This method is asynchronous. Add a listener for the
popstate event in order to determine when the navigation has completed.
Syntax
js
back()
Parameters
None.
Return value
None (undefined).
Exceptions
SecurityErrorDOMException-
Thrown if the associated document is not fully active. Browsers also throttle navigations and may throw this error, generate a warning, or ignore the call if it's called too frequently.
