@raisedadead I talked with @BerkeleyTrue about this a few days ago and he said could tackle it himself, and we set it to blocked.

Possible solution to this are:
Wrap user code in an anon function. const are block scoped so wrapping them a function prevents them from polluting the namespace of the iframe.
Pass the user code through babel so that the const's are transpiled to var's. We currently do this user code but not for script tags in html from the users input.

Those are two approaches, right? Which one would you prefer to take?

@ZZhaoTireless The second one would be best of the two
