the owner of the solution above was like you someday.

This is a more streamlined version of what I did. I'm glad to see I'm starting to improve 😭

Nice solution, I did almost the same but a few lines longer. This is how I first learned about the "Set" method.

For me to even think in this direction shows I'm improving gradually.

I wished I used a Set for this one. This solution makes me feel dumb. lol.

Greate job bro.

Thanks today i learned that spreading the Set inside the array will to same job as
Array.From()

Perfect!

This is general knowledge...

This makes me feel reaaaaaaaaaaaaally stupid right now. :( At least my solution worked, but this is art haha

Great solution

You didn't filter for [a-z] factor though.

Yeah, you can, cuz set's constructor takes an iterable object and string is iterable

could u ve done that without using the sort(), right?
