If it works on IE8, will it work on later versions of IE?

Question

Browsers

Hello. I'm testing the site. Tell me, do I need to download all versions of ie or can I just check for ie8? If it works fine there, then it will work fine everywhere? Or are there surprises waiting for me on version 9 or 8, and it is also desirable to download them?

If you need support for IE8, then most likely the TK is written illiterately.
Yes, you need to test in all versions. But it is better to limit yourself to IE11 and Edge.
