If you neglect some of the metaclass stuff, which I believe most people do, then Python is nearly isomorphic to JavaScript. I think the comparison is very fair. I also believe the reason Python is unlikely to ever catch up to JavaScript is the same reason that CPython will always be the dominant implementation - They've exposed so much of the C internals, that everyone is bound to the actual slow and single threaded implementation. JavaScript implementations in web browsers can do lots of magic behind the curtains because the majority of users don't rely on the actual innards being consistent from release to release.
