I was trying to figure out how to know the if the user can basically go back a page. I looked at history.length but it's not consistant browser-wise (it's 1 on all on a new page except Firefox which returns 2) and it also counts the pages that are forward.

I basically have a form with a back button that should simply redirect to the home page in case the user can't navigate back.

Why don't you use a browser checker library to overcome that inconsistence? – Dez Nov 14 '17 at 15:26

`history.length` returns `1` for a new page for me, Firefox 56.0.2. – Sebastian Simon Nov 14 '17 at 15:27

@Dez Do you have any examples ? – Calvein Nov 14 '17 at 15:30
@Xufox Might be because I did my tests on jsbin, but I can reliably use it anyway since it counts forward pages too – Calvein Nov 14 '17 at 15:31
