I like this solution with the in operator.

Why did I not think of this? So nice!

Both are getting there values from 'arr'. You can imagine this as nested loops. .find on the outside, .filter on the inside.

Very nice use of an array for the initial value. I want to do this for another solution now.

Here's what ChatGPT told me about this code.

"Overall, it's unclear what the purpose of this code is or what it is intended to accomplish, as it contains a lot of obfuscated and seemingly arbitrary variable and function names, as well as mathematical calculations that don't seem to have any clear meaning or utility."

I did not know the argument object existed on all non-arrow functions. Beginner kata was worth doing.

Omg, I tried to figure out the algorithm behind Math.random() when the solution was so simple haha

Very satisfiying once you solve it. I finally solved something with recursion and it was this problem :)

Logical OR operator is used as control flow instead of a conditional in this instance.

It returns the first truthy expression. If every expression were to be false, it returns the final falsy value.

You can imagine it as a door. You only need to open the door ||, to look for another truthy value.

Solved the short tests, but for the long test I get the error "Execution Timed Out (12000 ms)", my best guess is I would need to learn bitwise operators to make this more effienct?
