@aescling @vaporeon_ the python syntax forces a new variable to be added to the current scope, something the javascript IIFEs do not do

there is no need to perfectly replicate javascript IIFE behavior because it is impossible

@aescling @vaporeon_ what is wrong with having an iife that is a procedure can use again?

@aescling @vaporeon_ personally what i would do is

def iife(func):
    func()
    return func

@iife
my_func():
    print('my_func')

So that the original function still exists

@aescling @vaporeon_ whatever the return value of the decorator is becomes the value of the function you decorated

@aescling @vaporeon_ oh because it's calling _some_iffe

the pattern

my_func = decorator(my_func)

where you replace a function with a the return value of another function, is equivalent to

@decorator
def my_func():
print('my_func')


So we could define an decorator iife:

def iife(x):
x()

And use it like so:

@iife
def my_func():
print('my_func')


This is fully equivalent to the disgusting evil hack you just shared.

@aescling @vaporeon_ why are there parenthesis after @lambda _:_()?

@aescling @vaporeon_ what the fuck

@aescling @vaporeon_ how would I do it in python?

@maple i mean, it does look cool though

@vaporeon_ the vaporeon will always have C brain (sea brain?)

@vaporeon_ also node, npm, eslint, typescript, the horrible tendency to recklessly add large numbers of tiny packages to projects instead of copy-pasting simple code, and transpilation

also eval, the Function constructor, var hoisting, function hoisting

@vaporeon_ it's a neat little syntax that languages have been introducing lately to make string interpolation simpler.

Instead of String(x) + "-" + String(y) you do ${x}-{y} (I can't figure out how to add the surrounding backticks in markdown so just pretend they are there)

Python has a similar thing called "fstrings". In python it would look like f"{x}-{y}"

There are some interesting other features of the backtick strings in JavaScript that I don't use that I won't describe here.

every time i try to make ​ think c++ is bad and javascript is good the opposite happens lmao

@vaporeon_ reported.

@vaporeon_ IT'S BEAUTIFUL 🥹

/**
 * @param {character[][]} grid
 * @return {number}
 */
var numIslands = function(grid) {
    const seen = new Set;
    const R = grid.length, C = grid[0].length;

    let count = 0;
    for (let x = 0; x < R; ++x)
        for (let y = 0; y < C; ++y)
            if (!seen.has(`${x}-${y}`) && grid[x][y] === '1')
                (function crawl(grid, x, y, seen) {
                    if (x < 0 || x >= R || y < 0 || y >= C) return;

                    const key = `${x}-${y}`;
                    if (seen.has(key)) return;
                    seen.add(key);

                    if (grid[x][y] === '0') return;

                    crawl(grid, x + 1, y, seen);
                    crawl(grid, x, y + 1, seen);
                    crawl(grid, x - 1, y, seen);
                    crawl(grid, x, y - 1, seen);
                })(grid, x, y, seen), count++;

    return count;
};

@vaporeon_ a special javascript syntax that lets you declare and execute a function simultaneously :DDDDD

RECURSIVE IIFE SOLUTION :DDDDD

@coriander still love battlefield 1 tho

@coriander battlefield games are Clusterfukcs

@vaporeon_ It suddenly occurs to me that I, too, do not understand how refrigerators work
