Makes JS the fastest interpreted language by a long shot.
Bridges the gap between front-end and backend developers.
Consistent code between front-end and backend, also reusable.
People who hate JS typically have very little experience with it and can't get around its duck typing, prototypal inheritance, callbacks, and other functional aspects like first first class functions. They also get really confused with closures.
I'm guessing it's because they come from a language like Java and C++ and they see the familiar syntax but soon realize it takes more than 5 minutes to learn despite other similar people telling them it's a shallow language.

Shitty technology for losers who can't get into some normal one. Using js when writing back-end is silly, the technology has been invented for stupid hipsters and other subhuman shit. Also Node doesn't even have multithreading, it has so called asynchronous feature, but you won't have some shared objects in you app because of that and etc. Personally, I don't like js because os architectural errors and the world around it, it will die when web assembly releases.

Pretty much the same shit. Just use Express for your API, Mongoose for ODM, and serve your static files however you want.
>>53912704
The real problem I have with JavaScript and Node is that the documentation is always garbage.
Even fucking Google's Polymer API has shit documentation.
Nobody that develops for JS and JS accessories ever seems to have it in their head that they should document every little fucking thing, otherwise I'm left wondering what the fuck a function returns or how this asynchronous function interacts with this array of async functions and callbacks, because nobody documents exactly what happens to the callback, or what the callback as a function does.
MSDN documents are perfect in comparison. They may have too much goddamn detail but at least I know what I'm looking for is in there somewhere, instead of going on a goose chase for information that doesn't exist.
I personally prefer static typed languages (TypeScript looks interesting). With untyped languages like Javascript is easy to make a mess once your application starts to grow, especially if you have subpar programmers on your team.

If you weren't a retard you could learn and use more than one language
>>53912834
Well, then the question is whether or not it's better to have 1, 2, 3 or x number of languages for your CRUD app. I suppose you can use 2-3 languages but what's the benefit? Does it improve your developers' workflow? If it does, then okay, but Node.js was a solution for people on Rails and PHP. People that are usually webshits and not more formal software engineers and having them write in more than 1 language is probably against good judgment.

The whole Node.js ecosystem is pretty nice when it comes to creating web applications because it has modules for everything. Need a quick way to turn html into pdf and send it to AWS S3? Install two modules, bind them together with a couple of lines and that's it.
Also the very asynchronous nature of JavaScript is a blessing when it comes to API development. Couple that with functional programming style and your code is super easy to read. The same thing written in Scala would look like a monster from the deepest pits of the Abyss.
It's also worth nothing that with modern tools you can write generic functions to be used in the front-end and the back-end, import them to wherever you need and let the build tool handle the rest. No copypasting required.
There are more modern and nicer languages available out there, but it's hard justify using them in some cases if Node does the same thing three times as fast.

Rails dev here
Both Ruby and Rails are fucking easy to learn
Compared to JS where I never taught myself more than what I learned in a single module on web development at university. JS has loads of bullshit going on that I don't need to know about because all I do is manipulate DOM elements with jQuery, which is easy as fuck.
The point is, there's no difference in the amount you learn. If you use node then you're going to have to know JS really really well, and it's no more effort to learn something fucking easy like Rails.
>>53912704
>Makes JS the fastest interpreted language by a long shot.
That's because it's JIT-compiled and not interpreted. And it isn't the fastest JIT-compiled language by a long shot.
People who hate JS typically know that those properties are shit.

>>53915959
if you have a wrong node installation yes
anyway, just use sudo if you can't copy paste 1 line of curl call to install nvm
apt is mostly outdated, so dont use it to install interpreters. If you do the same with ruby (you should use rvm) or python (you should install it via virtualenv)
also, npm is not a standalone package since at least 2 years or more, so you just need to install node and you'll have npm
so.... why blame js if the problem is exactly between the keyboard and the chair?
does nodejs have co-routines yet?

STREETS
I like my node.js
Writing front and backend for small projects inside the same project folder feels really refreshing. Writing in just one language feels just right.
Sure javascript is not the fastest language when it comes to computing. If you had to write a server program which calculates a complex route on a map you would not use js but most of the time webservers just publish and transform data from the db. For this tasks node is just fine. The projects are very lightweight which makes coding a breeze.
Previously I was coding C# back-ends which was okay. But 99% of the time there was an enormous coding overhead involved and it still wasn't as fast as node. End of the story: node.js is here to stay.
>>53912744

Most node projects I have seen can not justly be called lightweight. Lots of tiny dependencies to get "nifty" functions and other shit because the stdlib is so lackluster, making it hell to maintain when things get dropped or whatever.

>>53913956
Coroutines.
>>53916863
Except if you actually know JS all these conversions make sense. You can shit talk a language all you want but it shows just how much you actually know. You're pretty much nothing more than a language shill.
>>53921626
It's a choice to add left-pad as a dependency. I would not.
>>53922995
They makes sense because they're specified, but who in the god damn motherfucking world uses this behavior I would like to know.
>>53923020
It's an anti-pattern to use implicit type conversions. Only a junior developer would code like that.
>>53922857

durr herp derp
I make 130k doing fullstack JS as a consultant.
Recently on my new project I've been moving to typescript. Angular 2 and nativescript supporting TS as a first class citizen will do wonders for its adoption. Plus the overhead it relatively low, you can add types progressively so new developers are not constrained by the type system.
That in combination with understanding promises/generators as well as observables and JS is a great language to get shit done. The real pain comes from developing with other developers who are mostly retarded, use callbacks everywhere, and abuse every dynamic aspect of the language.
I think Java was created to stop these retards from ruining things.(Most of /g/ falls into the retard category)
LuaJIT and the JVM shit on V8, as well as any AoT compiled language. JS (ecmascript generally) is far from being a good language even if it improved during those last years. Why would you use node at all? There's no proper reasons nor any use case to it. This is incomprehensible.

We hate JS not because of duck typing, but because of weak typing. == is completely unusable because it's not transitive and thinks strings and numbers can be equal. It also doesn't have a real integer type. Everything is stored in IEEE doubles.
>>53925161
>same language for frontend + backend

>>53927792
Doesn't matter how it's stored, V8 optimizes shit so well that while it looks like doubles to the programmer, it's really being stored in the best possible numeric container
