It's hilarious. Doesn't work in IE, in Edge the button to start doesn't show and if you go directly to https://2018.stateofjs.com/introduction/ the navigation and styling is broken.

And in 10 the floating squares don't even show up. And it doesn't have fall-back for browsers with no SVG support - really nitpicky but it is an actual problem.

Works just fine in Edge. And TBH that's good enough for me, I don't think supporting IE is necessary for a tech-enthusiast targeted site.
