qbjs & qb64pe compatibility and equivalent for other languages like Python?

[madscijr]

I'm finally getting around to being curious about qbjs - what features of QB64PE does it not support? 

I'm thinking that a fully portable interpreter that runs in a browser, even locally, would be great for playing with other languages like Python, without having to install them on your system. Is there a qbjs equivalent for Python, Pascal, Lua, or any other cool languages? 

Thanks
