Both website and compiled js not working

[dhasial]

I'm not sure what is causing the error message I'm getting. I'm on Arch Linux. I tried the normal website, I compiled it myself with the required libs using Emscripten. I also tried both versions with Firefox and Chromium. Both of them give roughly the browser console errors, the following is via Firefox:

*each newline is a new message unless tabbed

When simply using the website normally with a mouse, the experience is that clicking any links/"buttons" changes nothing.
