Perl! How could you leave that out!

True. Regardless of how disturbing I find it, Perl does qualify.

I think it's inarguable that Ruby and especially Python are somewhat inhospitable to functional programming as compared to the rest of that list.

No less hospitable than JavaScript, which was my point.

I disagree strongly w.r.t. Python as anonymous lambdas are heavily restricted there. I disagree less strongly but also somewhat insistently about Ruby where the distinction between methods and functions is warranted but thus involves more overhead.

Having to use "def" isn't the end of the world. You often end up naming your lambdas in a let in scheme anyway.

JavaScript is hospitable enough that you see entire applications written in a functional style. Where is the Python and Ruby applications written mostly in a functional style? I've never seen any.

I've yet to see entire JavaScript applications written in a functional style. Just because "map" is used more often than Python doesn't make it functional.

I'd agree with this point. I don't think Python, Ruby, or Javascript are particularly "functional", whatever that means.

Better at being both a functional and object oriented language?

> Better at being both a functional and object oriented language?

Well that's both subjective and ambiguous (subjective in the evaluation of quality in each area, and ambiguous because the meaning of "better at a and b" can be interpreted in a number of ways, such as max by min(a,b), max by average(a,b), etc.

But, given that, I'd say that several of the listed languages are better at "being both a functional and object oriented language" than JavaScript, including Scala and Ruby.

So where's all the functional Ruby code? I've never seen any.

> So where's all the functional Ruby code?

All over. Various functional approaches are basic core Ruby programming techniques.

Its not a great FP language because it lacks functional purity (like most Lisps, and, more to the immediate point, like JS) and the main Ruby implementations lack TCO (as, again, do many Lisps and, again, JS.)

But there's certainly a lot Ruby code using functional style.

Better than JavaScript anyway, pretty much all of them.

I didn't ask which are "better", I asked which are better at being both functional and object oriented at the same time. I can accept Lua, but the others I really need a good argument for.

They are all better at both than JavaScript. There is no feature that JavaScript has that the other languages don't, often in very similar shapes. The reverse is mostly not true.
