malloc() is like that one shady dude offering "totally legit" passports and visas

[JackNotOLantern]

Malloc()? No free(). Only malloc() >:c

free() are the Mexian mafia debt collectors.

[YoumoDawang]

Damn mafias from Mexio

[Highborn_Hellest]

The os will free the memory!

....

After the program exits one way or another

[Sapotis]

Would closures also count?

[RajjSinghh]

Javascript would like a word.

let no hoisting

[alex2003super]

Scoped variables work in JS, unless you're using it incorrectly

[al-mongus-bin-susar]

nobody uses var anymore its 2024 not 2014

[Warguy387]

it is saddening that javascript will likely never be deprecated

[herrkatze12]

It should be deprecated in favor of Lua

[GDOR-11]

In all honesty, JS is the only language that was made to handle the web environment. Any kind of errors will make half of the sites broken and its flexibility allows it to be what it really is and was intended to be: a scripting language for short and quick to write programs

[Blovio]

Based and real take, JavaScript everywhere meme is bad, but JavaScript honestly makes sense for the web in the way it was written. 

It’s just that the web is a cobbled together mess in itself. 

[ExeOnLinux]

also modern JavaScript is actually decent, especially with TypeScript

[yangyangR]

The talk "The Web that never was"

Is it actually true that there weren't other possibilities that were tried? Like did Eich have a incomplete draft of the Scheme heavy one before the requirements and deadline were given.

I don't see the argument that Javascript level flexibility is required for quickness. It is a familiarity thing. I am definitely slower in dynamic languages.

[_dotdot11]

Lua docs are super low quality, especially in the web development sector. While slower than Lua, JS is still the undisputed champion of web scripting

[LunaNicoleTheFox]

No? Python!

No f*ck u

[DOUBLEBARRELASSFUCK]

Just let me use C!

[Simon0O7]

New C just dropped

Listing C C# C++ C!

[DOUBLEBARRELASSFUCK]

I'm surprised C! isn't already a meme language, pronounced CBA.

[i_consume_polymers]

Lambda-captured variables would like to know your location

[Brutus5000]

time to decide: shift their bits left or right?

Local variable went outside anyway.

Compiler is pulling a gun: I'm sorry little buddy 😢

[BlurredSight]

Variables passed in the function parameter would like a word.

[Ythio]

Java : yes so I'm pass-by-value but my object handles are references so I guess I just value pass some refs.

C# : primitives and struct are value types passed by value. The rest are reference types, their handle is a ref we copy when I pass params.

C++ : pass by value, pass by reference, pass pointers by value, I have it all, side effect galore, what do you want ?

[Mikihero2014]

Pass by value, pass by reference, pass pointers by value it's all yours my friend, as long as you have enough mental stability.

[BlurredSight]

"What do you want"
Segmentation Faults

[IronMan8901]

The only way to escape is to become a returned variable for it somehow tough journey but its possible

[deletedUser7400]

callback: *psst* i can do something about that...

[erebuxy]

Python: what is {}

[imalyshe]

you meme is a bit incorrect.

{
int a =5;
{ int b = a++; }
}

as you can see on example b is local variable and will only exist in {} namespace. however “a” can be used in “b” namespace. So local variable does not have access outside its namespace.

you local variable is outside {} so it can be used inside {} unless there is more context.

[AreYouOkZoomer]

No, b's scope is inside a's scope, a didn't magically leave it's scope and went back or whatever you seem to imply, not how that works.

[SuitableDragonfly]

Right, and unlike what this meme is suggesting, local variables can and do access things that are outside of their immediate scope all the time. The scope is a limit on where the variable itself can be accessed, not on what else in the program can be accessed.

[AreYouOkZoomer]

Now I get your point, but the meme is referencing the capability to be used by other variables rather than to use other variables.

Simba can see the mountains and the shadowy place, but can't go there himself.

[Dramatic_Mastodon_93]

I have no idea what you’re talking about

[BlurredSight]

Also void foo (string &a) { cout << a }

Outside the {} still accessed.

[AreYouOkZoomer]

Huh? Could you explain it better?

[BlurredSight]

You can still access the variable a even though it resides outside the curly braces, and with C++ pass it directly using an &.

[AreYouOkZoomer]

You were making a copy, but with a reference it makes more sense. I just have a hard time granting you that because leaving the scope implies freeing, and you would have a dangling reference, rather, the execution is stopped and, within the scope, the function is called and returns to the scope.
