javascript - replaceState() vs pushState()

Question

I've been reading and searching for advantages / disadvantages between replaceState() & pushState(). Read also Mozilla's article, and this interesting test but still is unclear to me the differences.

Any one care to explain in what they differ?

Answer 1

replaceState() will change the URL in the browser (ie. pressing the back button won't take you back)

pushState() will change the URL, and keep the old one in the browser history (ie. pressing the back button will take you back)
