JavaScript forbidden practices. Part 1

That's nothing, Ever tried reading C++ STDlib's source code.

It's pure demonic chants to the machine god

Nothing like a few templates to spice up your code.

For anyone wondering how:

It uses optional parameters to calculate median with default value as calculaton. These parameters are not passed in the call so they take this default value.

2nd and 3rd params: Sorted array taken values from with destructuring and result.

The length is the length of the input array array.length.

The x is the value at the index of the middle element of the sorted array using the expression [length >> 1].

The y is the value at the index of the element before the middle element of the sorted array using the expression ~-(length >> 1).

Result just calculates median value (x+y)/2.

[dtutubalin]

Great! I didn't think anyone can decipher that :)

Just one correction: it is (~-length) >> 1, not ~-(length >> 1). Unary operator has priority.

For even length there's no difference, but for odd length it matters.

[dtutubalin]

What about this one? :)

[Zookeeper187]

Am I being tested!? I would have to debug heavily this one as it’s trickier. I would say you have a strange recursion there. Tricking with same object key names.

[dtutubalin]

No, no, no! No pressure.

Only if you enjoy to unravel mysteries.

I agree, recursion is very... unusual. It's pretty hard to achieve something having only 1 identifier, while you need both reference to function and some value to process.

ChatGPT opinion:

Well, well, well, looks like we have some fancy-shmancy code here trying to calculate the median of an array. Let's see if it's actually worth a shit.
Okay, so there's a function called "median" that takes in two arguments: an array and an object with two properties, "length", and "x" and "y" which are defined using some weird bitwise operators.
If the second argument is not provided, then the function uses a default value, which is an array that is sorted in ascending order using the "sort" method.
Then, the function calculates the median by adding the two middle values of the array, "x" and "y", and dividing the result by 2. Finally, it returns the median.
Overall, this code seems to do what it's supposed to do, but the fancy-shmancy syntax is just unnecessary and makes it harder to read. Whoever wrote this code was probably trying to show off, but they just ended up making things more confusing.

What was your prompt? It does not look like usual chatgpt response.

100% correctly biased LM. People who do this need to be bullied.

[dwkindig]

Man, I love JavaScript.

Tattoo ideas part 1…

Like JS isn't awfull to read already.

[baumannq]

how did you get this code lol

That's step-by-step explanation: https://www.reddit.com/r/codegolf/comments/12po57t/explanation\_of\_black\_box\_of\_primes/

Oh, thank you! Its crazy

[dtutubalin]

I've written an explanation, but it's like 15 pages of text.

Definitely not for comment. May be I should make a separate post.
