Node.js is a shitshow just like everything else created by code camp tier javascript webdevs.
>>54837814
>is node.js /g/ approved?
As you can see from this thread, absolutely not. Quite the opposite. If, however, you instead ask
>is node.js useful and practical for creating web application backends?
the answer is yes. It's extremely well supported and in wide use by everyone ever. It has many shortcomings but tooling mostly makes up for them.
It's possible to create shitty codebases with it, but also possible to write large, solid, readable, maintainable, performant ones. Tip: Use ES6 religiously, use Promises to minimise callback hell, don't be afraid to make very liberal use of the extreme number of tiny support libraries instead of re-inventing the wheel, and use a testing framework.
I've been using it for work for the last ~6 months. I was unhappy at first, having been convinced of its awfulness by all the internet memery. The truth is that, if you know what you're doing and do things right, it's absolutely fine and in fact has many advantages.

no thanks
>>54838999
Lots of errors and bugs in the language, stupid shit like callback everywhere, too much syntax sugar (JS is NOT class based ffs, its prototype based or whatever thats called), took the worst style of Java (camelCase...) and inserts fucking semicolons if you dare to use allman style everywhere. And thats only 10% of whats wrong
>>54839315
Yep, that happens. Pic related. But it's perfectly fine in practice, unless you're using a worthless editor.

I can confirm, those are god-tier tips.

I reached the same conclusion. ES6 really helped make the language decent.

>Don't fight JS on truthy/falsey
Agreed. Once you learn JS well, the usage of == versus === will be second nature.
Don't pay attention to people who say to always use ===. There are cases where == will work fine, and is actually a more concise way of expressing the semantics you would want.
Sure, it's a bit more complicated that it would have been if they had designed the language better, but the rules aren't very hard to learn.
>>54839651
Agreed, they have to work on it. But as your link shows, they're addressing the problem by introducing some policy changes.
>>54838759
>make very liberal use of the extreme number of tiny support libraries instead of re-inventing the wheel
Please don't. It's not reinventing if you just put the parts together.
>>54839187
All of those things exist with other platforms though. What about technical advantages that actually make Node better for writing x, y or z types of service?

>Java failed because it is too complex, webdevfags couldnt understand it
Java is shit easy, its like sticking together lego blocks. It failed because all the libraries are built into the language, Java is a platform that traps you into only using Java for everything and having to wait for people who maintain the Java platform to provide features

It's more than that if you consider the lack of proper multithreading.

JavaScript is more efficient than Python. Just drop the meme. JS is the scripting language of the future.

no

no
>>54843346
If Python were standardized (like ECMAscript) and PyPy would support 95% CPython libraries it would make sense to compare them directly. But these assumptions do not hold. I like PyPy though and I have used it. The 10-15x speedup is very real on my data manipulation tasks.
>>54842920
>But I digress. Quick visual projects in javascript can be fun.
Yup. And once you are done with the exploratory phase you can always port to C++.
>>54837814
absolutely not. they are braindead retards still doing php.
