react is dramatically better than every other js thing i've ever used and comically better than every frontend js framework

i dont even give a gently caress about shadowdoms or speed it's just really good at displaying things in the browser

really want to give relay/graphql a shot too

ive been working with angular for almost a year have an OK grasp i think. ive used react for a total of a couple days and it already makes way more sense. despite the small area covered by the library, i dont feel like im missing much. like so much of angular seems completely unnecessary to me

elm is very cool but unlike react, there's almost no way i'm convincing anyone to start using it

there's a flux implementation/variation called Redux that turns FB flux into the Elm architecture pretty much. that + typescript (which supports JSX now) + an immutability library might get you kinda close.

Yesterday morning they told me to make a tiny thing that sounded like it was just going to be turning a batch file into a program with some checkboxes that would then run the individual commands in the batch file depending on whether the checkbox was pressed.

Today I went home still not knowing why a setup.exe I was trying to start with CreateProcess didn't work right at all while it worked just fine if i doubleclicked on the batch file that invokes it.

Actually the point is that functional languages make it really easy to write a bad sorting algorithm that looks kind of like quicksort but isn't. Similar to when people try to write a prime sieve.

Quicksort is an in-place sorting algorithm, if it's not in-place it's not actually quicksort.

I don't know what any of that means so ok

extension methods in C# are pretty much exactly the same thing as categories in Objective-C, except with confusing syntax

in ObjC you use very similar syntax to add a category to a class as you do to define a class in the first place, so adding categories is completely natural

in C# though you have to write an extension method as function that takes this as a parameter and so on, even though at the call site it looks like an instance method

like I can add a category on the system NSSound class like this

code:


// NSSound_ButtNoises.h
#import <AppKit/AppKit.h>

@interface NSSound (ButtNoises)
+ (instancetype)fart;
- (BOOL)playSeveralTimes:(NSUInteger)count;
@end

// NSSound_ButtNoises.m
#import "NSSound_ButtNoises.h"

@implementation NSSound (ButtNoises)
+ (instancetype)fart {
    return [self soundNamed:@"fart.wav"];
}

- (BOOL)playSeveralTimes:(NSUInteger)count {
    BOOL played = NO;
    for (NSUInteger i; i < count; i++) {
        played = [self play];
        if (played == NO) break;
    }
    return played;
}
@end

and I can use the methods it adds just like any other NSSound methods

code:


NSSound *fart = [NSSound fart];
[fart playSeveralTimes:219];

Quicksort is an in-place sorting algorithm, if it's not in-place it's not actually quicksort.

Singly linked lists being ubiquitous is easily the biggest potential gotcha in functional langs (or at least ones that aren't lazy). It seems fine at first, makes things much easier. Then a few months down the line in one case out of hundreds they're absolutely not okay.

"is slow" isn't a gotcha, is only rarely a problem, and it is easy to figure out when it is.

defaulting to the safest and most versatile but least efficient data structure is the correct design choice.

make it work, then make it right, then make it fast.

AWWNAW posted:

we aren't comparing objc class/method definition syntax to c# syntax here. of course objc's syntax looks "quite more complex" if you aren't used to it

conceptually, objc's way of solving this problem is simpler. in c# you have to define a separate class with a new name and a bunch of special methods (why are they static? you're trying to write instance methods) in order to get this result. you also simply can't add class extension methods at all.

in objc you just define a new interface for the exact class you are trying to add methods to, with a category name in parens (and you use this to define private methods, too) and then you define methods like normal. they just show up on instances and the class object when you include the header.

swift's method involves you defining the extension with the keyword "extension" but is also conceptually simpler

another thing you can't do with c# extension methods that you can with at least swift's (idk about objc) is declare protocol (interface) conformance. in c# if you want .net's List class to implement whatever bespoke artisanal sequence interface you came up with, you have to subclass List and use that subclass everywhere. in swift you just use a class extension and then magically all instances of that type conform to the protocol

it's used, yeah, like:

code:

{ 
int[] data = new int[BIG_NUMBER];
// call a jni function to fill data
// do stuff with data
}

and the size is a constant.

im coming to this from a c/c++ mindset and if i saw a

code:

 
{
   int* data = new int[BIG_NUMBER];
   memset(data, 0, sizeof(int)*BIG_NUMBER);	
   /// stuff
   delete[] data;
}

in a time-critical section of code i would start thinking along the lines of 'hey maybe we can hoist the allocation out and only do it once'

but (a) idk if the jit is smart enough to do that sort of thing and (b) see earlier comment re: not being set up for profiling
