> Please, no book, but I would be happy to read one concrete example of why Ruby/Bundler is substantially better hands down.

One illustrative example might be the existance of Celluloid. The idea that you as a developer of Ruby apps can swap out the I/O system to something that's arguable better than what what the default style is. The reason Javascript can't do that is because it doesn't have synchronous I/O, nor multithreading, it's simply lacking those primitives.

I don't like the callback style, and I'm not entirely sold on promises.

In any case both those 'issues' might be close to fundamental differences between Ruby and Javascript but if I'm honest, this is going to sound like I'm back pedalling, but in real measurable terms they won't affect the quality of your codebase. I don't think porting a library from Javascript to Ruby would solve any real problem (as Haskell would), and it would result in your library being slower.

The dozens of little things that make Ruby a more pleasant language, they are what keeps me on the Ruby side for most projects.

> I am quite aware that some Haskell lover is probably laughing and sticking their nose up at this entire conversation.

Haha, I'm actually also a Haskell programmer. My top 3 is Ruby, Haskell, C# ;) I do Ruby and CoffeeScript for a living, build games in C# as a hobby and am building a C compiler in Haskell as my secret plot to take over the world. I have a sideproject that's a REST API in Haskell as well, but I'm not 100% convinced yet that Haskell is right for that.

Easy proofs for Haskell superiority: You can compile into a static executable. You can make the typesystem enforce the correctness of your user input parsing (this is crazy effective in JSON Apis, so effective that I now use Grape in Ruby to do sort of the same thing). Its lack of OO and focus on processing data leads to very clean architecture. Its level of abstraction is so crazy that they can actually swap out their entire I/O system for another one without changing any application interfaces, this one blew my mind, it's the change that makes GHC 7.8 run the Warp webserver twice as fast. They actually changed it so the 'fork' system call does not actually spawn a new thread, it spawns a fiber that's run in an event loop type system, and changed all the I/O functions to use asynchronous I/O on that event loop. All of this without changing a line in Warp, they just transparently made every traditional Haskell use modern I/O principles. Academics man, they're smart ;)

C# is cool because it manages to stay clean, fast and structured even though it's super powerful and implements almost every paradigm known to man. It's a statically typed compiled language with near native performance, yet code in it is nearly as succinct as Ruby. If I'd jump ship from Ruby because of performance reasons, it'd be to C#, not Node.js. Provided it runs smoothly on linux of course ;)

Haha; I got a kick out of reading that. Nice!

I'd be interested in what you are finding there. I have been wondering if I should start moving toward Haskell or Erlang/Elixir. So far, I've spend much more time with Erlang and Elixir and I'm liking it.

What has given you grief on the Haskell side?

> Easy proofs for Haskell superiority...

Wow! I had no idea Haskell was so flexible. Perhaps I really should spend a bit more time there. I've never read anywhere else about this level of flexibility in Haskell.

If nothing else, this conversation was well worth it just for that...thanks :)

I wouldn't know about that, I only took a glance at Erlang, didn't really like the syntax but Elixir seems really pretty (Rubyist speaking of course ;)). I'm also a bit put off by how Erlang has distributedness integrated in its language, I didn't really try it out so take this with a grain of salt, but I have the feeling that it makes it more of a domain specific language, and it perhaps would be in the way of generic programming. I also had to deal a lot with a misbehaving RabbitMQ at work, so I might have channeled my incompetence into a opinion of Erlang :P

> What has given you grief on the Haskell side?

Well, both web projects I did using the Scotty framework, which I adore. The first was a web adaptation of a school project, you can take a look here[0], I like that a lot. But the second project was a docker container provisioning tool, and it had to do a bunch of stream processing and such. It's not that the libraries are bad, but there's a lot of research being done and there's 5 different popular I/O stream libraries, with various amounts of super high level abstractions, it just slowed me down a lot having to research all of it and dealing with some really high level Haskell.

That's one down side of Haskell. There's an easy way to do things, with nice pure functions and a I/O monad here and there. And there's the hard way of Haskell with monad transformers and generic type classes and what have you. You can easily avoid the hard stuff, but if you get sucked in you'll feel like a total dumbass and it'll cost you time and motivation :P

No problem, thanks for making me back up my ludicrous opinions ;)
