Could someone explain why/how the or works

Javascript does not guarantee object property order so I don't think this is a reliable solution.
See https://stackoverflow.com/a/5525820/2964461

I don't understand how this solution keeps the right order of the sentences. Could anyone explain it to me, please? Thanks

For non-english speakers, it's just a bunch of latin letters.
It's cool to read programs as plain text, though.

poetic, though

read the last line, thats just sad lol

I always forget to inline and return the index I want all together. This makes it much cleaner. 👍

This shortcut is often referred to as an "immediate array access" or "anonymous array declaration with immediate access". It's a concise way to define an array inline and immediately access a specific element from it without assigning it to a variable first. It's commonly used in situations where a temporary array is needed for a single operation.

What is this kind of shortcut?

what does the [...this].eqAll() mean? if someone could break this down on what is going on that would be great! thanks in advance.
