What is the purpose of the event window.onpopstate?

A. When a state object is replaced

B. When a state object is added

C. When a state object is removed

D. None of the mentioned

Answer: Option C

Solution(By Examveda Team)

The window.onpopstate event is fired whenever a state object is removed from the browser history, which occurs on browser “back” or “forward”. State objects are persisted on the user’s hard disk between sessions, which is a nice feature. The object passed into a call to pushState or replaceState is provided as the state property on the event object in the “popstate” event.
