This basically means "Give me an array of letters from sorted input array's first item" ;)

hey could you please explain me why did you transform the time of the day in millisceconds? Thanks!

You need to wrap those values with brackets [], because what you posted isn't an array. Using "3 dots" on a string returns an array of characters.

See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_syntax

i don't understand why the three dots (...), return us an array and not something like this :
"paolo","zarate","azorsa","daniel".
i replaced the ...s with those values: "paolo","zarate","azorsa","daniel", to see what is going on, but i gives me an error.

limited testing. it's essentially correct, even if somewhat incomplete.

HOW DID THIS PASS ???

very clever

@rowcased
From my knowlage leaving magic numbers is a bad habit/practise. My descriptive name of const isnt the best, maybe I should name it better, but still this is not a "magic" number. Maybe I'am wrong, correct me if I'am.

honest question: does it make it any less magic if you assign it as a const var as you did in your solution?

86400000 - magic number ;/

That's the amount of miliseconds in a day.

What is the significance of 86400000?

Can anyone tell me how this would compare to just using the method in terms of efficiency?

Wouldn't this require more space to make a copy of the method or is there more to it?
