Except that for historical reasons, js is a very rushed/badly designed language. More precisely it mixes moment of brillance and very stupid design choices.

Ruby, Python, Lua are in term of language design way superior. Coffeescript and co emerges because it was more reliable to have a complex stack than to use the JS language directly.

That's the only high-level language that produced this situation. Python/Ruby & co are not perfect but good/reliable enough. You don't program in a another language that compile to python to avoid its verbosity and its traps.

If python had been choosen for the browser, we would have used for the last 15 years : module, sane scoping rule, classes, iterators, etc. Yep, that's something that it ecma6 without the ugly baggage.

15 years, damn it.

So no, please give at least Python in the browser and let people experiments with other language design choices and let them find something superior to Python. At one moment, it will be obsolete like any other tool. I don't want to be forced to use it because it is the only choice.
