There's a lot of stuff other languages can do that JS can't.
For example, classes, which a lot of developers prefer to use
in favor of the weird object system in JS.
If you don't change the prototype object, then it is mostly
similar, but more flexible. Functions are constructors and
prototype objects are class definitions. You could also use
typescript, typescript playground is quite fun. It allows you to
explore the JS output in realtime.
You can kinda do classes in JS, it just isn't pretty syntax. In
the D to JS toy I did, I just did an array of function pointers
to handle the virtual functions, similar to how D is compiled
to machine code.
It'd be fairly ugly to write by hand but when converting
languages, it works well enough.
Huh? Dynamic languages have dynamic lookup, how is that different
from virtual functions?
