ahh right ur clever

Note: If the input string contains no digits, this solution will return a 0, which might be unexpected behavior. By contrast, parseInt() and unary + coercion will result in NaN.

its so nice but you have to knew these methodes then you can solve this kata;

best of the best =D

lol

wtf?! 😒

Great!

This is the most succinct solution, but as I have seen and noted before with other kata, the requirements imply the need to change the array in place:

removes duplicates from an array of numbers and returns IT (my emphasis)

In a real-world, professional situation, we would seek clarification of the intended requirements before proceeding, and we would update the written requirements accordingly.
