No

so in Javascript Sets and Maps are hashed with ===, which checks for refrence equality. You cant overwrite === so if you want to have a Set of a custom data type, you're fucked! What's more, Javascript's === semanticas are totally fucked:

 
let a = [2,3] 
a === [2,3] // false 

It is therefore nearly impossible to use a Set or a Map in Javascript.

The C++ language never rammed any features down your throat. Let’s not confuse the languages stance with that of the zealots in that community. You never had to use those OO features if you didn’t want to.

But they were so tempting, weren’t they? They glistened like gold and were so much fun to use. You were young. You didn’t know any better. You needed the money. And it was fun too. C++ looked like it could fulfill the dreams of programming in the large.

At first, the changes start in small ways. The comment style changes. /* */ evolves into // . Shortly thereafter variable declarations are sprinkled liberally in the middle of functions. Small and simple. Yet it hit a relevant sweet spot with many developers.

Then the inevitable happens. References find their way into function declarations. The inexperienced developer begins to dabble with function overloading, which results in the requisite name mangling. Now the peer programming languages from the past have a huge barrier to cross.

Structs turn into classes with virtual functions. Classes pick up non-trivial constructors, and critical high-level functions start throwing exceptions. Then comes the mind-bending multiple inheritance designs. When this phase appears, the old-school programming languages have no hope of participating.

By the time the metamorphosis is complete, it’s too late. There’s no turning back. The beauty of this evolutionary process is that as the code base becomes more entrenched with C++-specific features, it becomes harder to get out. The code begets further C++. Its existence serves as the accelerant in the process.

Given the difficulties created by the linkers on most modern operating systems, C++ has to go through extraordinary gyrations to make its function overloading available to mere mortals. But it’s the same silliness that serves as its defense. Once you have mangled function names, there’s no hope for the rest of the classic languages to feel like equals.

Not an excuse in the modern age, you can get an answer to just about any question on the internet (but make sure you take the time to actually understand the answer and implement it yourself instead of just copy+pasting some pajeet's snippet from stackoverflow). Besides, if you don't push yourself how do you expect to ever improve?

No, I understand why it doesnt work. It checks for reference equality. But consider the following code snippet.

Dont you think there's something wrong with that? The way to get around it seems to be strignifying your values:

let s = new Set(); 
s.add([1,2,3].toString()); 
set.has([1,2,3].toString()); // true

but then your values() are all useless!

In that case, I'd recommend Scratch. It's easy to learn, and easy to shed off once one starts learning real languages.

I rail against python because it has a lot of idiosyncratic syntax and best practices that won't help a beginner anywhere outside the realm of python.

It's better to start off with a language which has a more widely applicable syntax.

But if all you want to teach through Python is conditionals, loops, and objects, then there are many better options available.

If it's so powerful, why doesn't it have a way to deduce function type from capture-less lambda expression?

auto f = [](int &dst, int a) { dst = a; }; // obviously of type "void (int &, int)"
using FctType = decltype(f); // FctType is not "void (int &, int)" but some implementation-defined functor object
using RetType = decltype(f(dst, a)); // RetType is of type "void", the type of the lambda return

>>61215692
What's your problem, the fact that it won't implicitly decay to a plain function pointer?
Because you can use unary+ for that.

>>61215762
Decaying the lambda will only give me a function pointer type, std::function instantiation requires a plain function type. decltype(*fptr) would only give me a reference to the function and std::function does not accept such a type.

Wrong.
The type of a lambda is always an implementation defined function object. It only contextually converts to a function pointer.
You can deduce the type of a lambda, it'll just deduce to the actual type of the lambda (which is better), rather than a function pointer.
Why is it better? because lambda objects are empty objects, which means EBO (Empy Base Optimization) can be applied.
It's what allows an std::unique_ptr with a custom deleter defined by a lambda to still be only the size of a single pointer rather than 2 pointers.

Come up with 5 things wrong with OOP


See? You can't, because it's perfectly fine.

I found out how to create an anonymous class on the heap!

// Example program
#include <iostream>
#include <type_traits>

struct HelloInterface
{
    virtual void sayHello() = 0;
};

int main()
{
  struct :HelloInterface
  {
       void sayHello() { std::cout << "Hello from anon"; };   
  } *hello_impl = new std::remove_reference<decltype(*hello_impl)>::type();
  hello_impl->sayHello();
}

>>61215839
>because lambda objects are empty objects, which means EBO (Empy Base Optimization) can be applied.
don't they contain vptrs?

>>61215839
>The type of a lambda is always an implementation defined function object. It only contextually converts to a function pointer.
Yeah, I was aware of that, but went a little overboard, because what I actually want is to get the type "void (int &, int)" out of f to instantiate std::function with that type (I'm actually working on generic callback execution).
Right now, I'm here:

auto f = [](int &dst, int a) { dst = a; };
using FctType = decltype(*+f);
std::function<FctType> callback(f);

Which doesn't compile because FctType is "void (&)(int &, int)" instead of "void (int &, int)".

>>61215874
No. Each lambda object is unique to the specific lambda it is created from. They are not virtual, there are no virtual calls involved, there is simply no data stored in the object whatsoever, they are empty.
http://en.cppreference.com/w/cpp/language/lambda

I should add that you should avoid the use of std::function. Don't use it unless you really have to.
If you need a callback, either accept a function pointer, or use auto or a template parameter to deduce the actual type of the lambda, which gives you empty objects with an overloaded operator(), which you should prefer because it can be better optimized.

>>61215904
This one compiles for me:

#include <functional>
#include <type_traits>

>>61215904
I don't know how to fix that, but is there any reason why you definitely need to use std::function?
You should avoid it, they can perform costly heap allocation.

Instead do something like this:

template <typename Fn>
void foo(Fn fn);

to deduce the type of the actual lambda object and use that instead.

And if you really need type safety:

template <typename Fn, typename = std::enable_if_t<std::is_convertible_v<Fn, void (int&, int)>>> // Or use a static_assert in the function body.
void foo(Fn fn);

At the cost of readability.

>why you definitely need to use std::function
I don't actually have any kind of use for this. I kind of piggybacked on >>61200358 and wondered how you could pass a lambda with capture to a function, given that in that case, the lambda won't decay to a function pointer. That's how I ended up with std::function.
Treating the case of capture-less lambdas was related in such a way to experiment with type deduction.

>>61216054
Change it to

 using FctType = typename std::remove_reference<decltype(* + f)>::type; 

, then works for C++11 too.

Reminder that C++ is the best language because speed matters more than bloat, elegance, and programmer comfort combined. The ONLY reason C isn't better is because it's so far backward on the "programmer comfort" scale that it actually manages to fucking break the scale and become more important than speed. That relationship happened between assembly and C, it happened between C and C++, and that's the last time it ever happened; all languages since have been unnecessary programmer luxuries that have slowed down our software for decades as a direct consequence of intellectual gluttony.

What's the closest equivalent to QBASIC nowadays? I spent countless hours in my childhood writing shitty games and demo graphical applications with it. It was a simple language that allowed you to type whatever program was in your head without caring too much about syntax or shit, but at the same time you felt in control of the machine. Nowadays all popular languages feel targeted towards work (web, databases) and nothing seems genuinely fun, everything feels high level as fuck and too abstracted from the bare metal. Even Visual Basic is now a monstruosity.

Do you actually mean lunix? As in, LUnix? https://en.wikipedia.org/wiki/LUnix
Because if so, your best bet is 6502 assembly language. Pretty sure LUnix doesn't even have anything else. I guess you could look online for a C compiler hand-rolled by some neckbeard somewhere.
On the other hand, if you meant Linux and were just memeing, Racket is pretty good for beginners trying to into games. There isn't really a language suitable for beginners that has libraries available for apps. The industry standard is Java for Android and Swift for iOS, and neither of them are particularly beginner-friendly. I guess you can kind of do app programming in Ruby, but its facilities for that purpose aren't as developed.

If there were an implementation of C geared toward 8-bit architectures, would it literally just have char? Like why even have int, short, and long, they're all just gonna be char anyway right?

assert(CHAR_BIT == 8);

Please explain

>>61217920
>Individual bytes don't actually exist on most platforms
Individual bytes DO actually exist on all platforms since by definition the byte is the smallest possible addressable unit.

>>61217954
yeah and that gets loaded into 8 bit registers
oh wait it doesn't
it gets loaded into 64 bit registers


>>61217955
As an addressable unit, a byte exists.
Beyond that it doesn't in most systems.
It's just the minimum unit of difference in memory addresses.

>>61217979
>yeah and that gets loaded into 8 bit registers
assuming

>>61217920
>All of your chars on most computers are actually 8 bytes or 4 bytes.
This is actually semi-true. A char * or char [] will obviously not be padded so that every element is int-aligned, that would be retarded. But once you extract an element, and/or if you just have a plain individual char, chances are it's actually being passed around and manipulated as a chunk as big as an int.

>>61217544

>>61217979
>yeah and that gets loaded into 8 bit registers

The size of extended registers isn't the size of a char. x86 can force bytes to be loaded using al, ah etc. The fact there are extensions doesn't change the fact the byte, in fact, does exist.

That's it senpaitachi, I'll never touch Clojure ever again.
Dynamic typing is driving me insane. I'm sick and tired of 'ClassCastException cannot cast IFn to LazySeq' with the most useless stack trace one could ever imagine. I know there's a library available for optional type checking, but it's a complete joke compared to full type inference. Besides the lack of a static type system, it's insanely slow at runtime. Java is slow, but Clojure brings it to a whole new level. I don't mind the (((parenthesis))), but using whitespace like Python and Haskell does is much more readable.
Sorry RMS, I failed you. Now I'm back to Haskell.

I'm going to prove in nine lines that C is garbage.

   assert(sizeof(chars) == 5*sizeof(char));

you first

Good example of why we can't have anything nice is Go.
Old Unix guru.
Instead of making "good C" he makes dumbed down language with GC where you need to type shitload to implement the most basic stuff.

Its not so much a feature for XYZ as it is a way to program everything.
Took a bit to remember where this quote was:
"To use types to help us write programs, rather than to use programs to help us infer types"
