Interesting issue. The problem here is a naming collision on Symbol.

Your code will work if you rename your Symbol class to MySymbol or anything else. Your class is conflicting with the built-in JavaScript Symbol object. Specifically, it creates trouble with the shim.js file in the p5 core.

Agreed with the above! I think a secondary root cause of this issue stems from the 'index.html' file in the sketch you linked for the web editor. Within that file on line 8, it seems like you're using p5.js version 0.5.6 instead of 1.6.0.

Hope this was able to resolve your issue! I'm going to close this for now, but please feel free to reopen this or create a new one if it still persists for you.
