JS has lots and lots of fundametal issues. Weird OO implementation (argue all you want but prototype inheritance is not what the prevailing wisdom is on how to do OO), no type system (at least give the option!), no packages/modules, no generics.

Don't people want dev tools to better help them building and refactoring web code? Web dev is like 15 years behind server development.

Of course some of these things are being fixed (e.g. modules are being added; there has been talk of optional types). At least when Google or Microsoft aren't dragging their feet and sabotaging the process.

As for generics, I'm not sure what you're looking for there; it's pretty simple to write generic functions in JS, or indeed any language with duck typing, no?
