It's pretty good and surprising powerful.

JS is a functional language, the only scope in JS is functional scope. Functions are first class and can be passed and imported. There is no module system in JS because it doesnt need one, function scope is so much better than namespaces or class types. JS is a typeless language, you can connect anything with anything without declaring or casting types. Functions in JS play the role of objects more than objects. Prototype OO works hand in hand with the first class function nature of JS. Its an outstanding language that fortunately became the default language for all browsers.

>>57016344
and for javascript, for which your operating system has to come with a bloated js interpreter...

>>57016356

Ok, good to know. It is in fact portable by your own admission.

>>57016431

If JS is a functional language by that criteria than so are C# Python, Ruby, and C++.

Functions are not as first class in C#, Python, Ruby and C++ because they are connected to classes as methods and so are not as passable as an individual object, lambdas and blocks in those languages dont have anything near the power of JS functions

>>57016535

Nice inaccurate portrayal of history.

You can write an OS in Brainfuck or even in a BAT script. Does it make them universal languages for every problem?
By the way, we already had a language intended to unite everything and to be a universal language. Does PL/1 name say anything to you?

>>57016622
>>Node is made Im not sure why
you answered your own question in the bullet point above:
>> SPAs become a thing like gmail, some people attempt to make these with just jquery. Its a huge pain in the ass
node made SPAs no longer be a pain in the ass

Returning a function object doesn't stop c++ lambdas from doing anything you can do with them in any other language. You can close over values and pass them around freely (bearing in mind object lifetimes when capturing by reference).

I'm eager to hear more about the special "power" of js lambdas, though.

>Returning a function object doesn't stop c++ lambdas from doing anything you can do with them in any other language. You can close over values and pass them around freely (bearing in mind object lifetimes when capturing by reference).
Im sure you can concoct a Rube Goldberg simulation of function objects in C++, good luck finding anyone willing to deal with that kind of bullshit

>I'm eager to hear more about the special "power" of js lambdas, though.
the "power" of js lambdas is that it doesnt need lambdas because functions are already individual objects, there is no need for a nameless version of function because they are all nameless and accessed by reference by default

>>57016789
>Im sure you can concoct a Rube Goldberg simulation of function objects in C++,

I don't even understand what you're trying to communicate here. Function objects are already part of the C++ standard and are integrated into the language and are easy to work with. I use them all the time.

>the "power" of js lambdas is that it doesnt need lambdas because functions are already individual objects, there is no need for a nameless version of function because they are all nameless and accessed by reference by default

What is the practical upshot of this for the programmer apart from more runtime overhead? Javascript function objects don't do anything more than higher order functions in C++, Haskell, Go, etc.

>>57016722

Not sure if that was the reason why Ryan Dahl made node.

Im sure you do, try finding someone else stupid enough to think that C++ is used for this purpose, Im not even going to waste time responding to this delusion

lol

<roll eyes>

go comes close but still theyre still tied to structs and dont do a lot on their own
>etc.
there is no etc

>>57017264
You were asked a question; why bother typing so much if you aren't able to answer?

What can I do with javascript function objects that I can't with any other language's?

>>57017312
literally nothing

>>57017312

He's talking out his ass.

Javascript is hardly a functional language. Its not based on lambda calculus, it doesn't have Tail Call Optimization, every type can be null, no immutable data types, statements instead of expressions, etc.

Javascript is as functional as Ruby/C#/C++/etc.
