This program will not run as intended on repl.it because the runtime on repl.it is still the pre-release 2 version (it should correctly error with
error: Uncaught ReferenceError: ErrorEvent is not defined since the
ErrorEvent was added globally in the third release candidate). you have to clone from the git repository and run it yourself.
Besides that, there are definitely some rough edges, mostly due to dejs and import statements i am working on polishing up. I was only able to work on this today - i plan on doing the final polishes really soon.
