Hmm. I verified that the MDN isn't just out of date by testing in Chrome. I can't remember the context I was using that snippet in precisely, but I do remember it was designed to run in IE10+, Chrome, and Firefox.
I may have just been using it so I wouldn't have to escape all my backslashes for a string.
Another one I just remembered:
Wow
It looks like the escaping only works in FireFox according to the MDN docs, RegExp.prototype.source (see Browser Compatibilty section).

I tried in Chrome yesterday and it doesn't error out, but it just doesn't escape.
