It's probably a brittle solution, but for the strings provided ...

this one is the GOAT

there is actually no need to save into variables the functions in our answers to these exercises, as we're not asked to then use them as parameters in higher order functions, so we can use a function expression, rather than a function declaration (plus, especially with the concise arrow syntax, we can use functions diretly as argumemts in other functions, or define and call them at the same time as an IIFE, eg. ((n)=> {console.log(n=5);}10); that logs 15)

Your codes are very clean

KANYE WEST!

Love it. Way more succinct than mine.

That's a great solution

took me 10 seconds to understand it

I know thank you

naming conventions should be followed, code should be readable. using e and v is very obfuscated

ou yeah

dirs is an accumulator which has been initialized as []

Sorry, first time commenting, already marked as spoiler. You could review my code, mine have never been reviewed. Thank you.
