No biggie. If it is, then it is.
When or how will I know that this kata should be deleted?

Changed the description to ask only for the first longest substring and added a fixed test for that.

About the duplicated kata; I think that even if it is a minor change to return the actual string insted of the size of said string, they presents two different scenarios. And that validates the existence of this one.

Altenatives are:

• Asking the other author to change their kata to ask for the first substring instead of the length and invalidating 300+ answers.
• Not allowing a new kata with a different reason to exists (this one) just because it is similar but not equal.

Don't take me wrong, if I'm mistaken, then thats it. You are the gatekeepers of this place :)

mybad, fixed

also might be wise to change it to 6kyu. Will keep an eye for feedback and change it if necessary.

Noted. I'll add that specific test and update the description.

also: eslint-no-semicolons

english no bueno
l'll give it a second look. All suggestions are welcome

fixed

done

done, hope you don't mind I used your solution as an internal validator inside the random test generator

by bad, I see what you meaned about the test. Fixing it

thx

Thanks, did not know that.
I'll update it and republish

Tests now validate spaces as valid (repeatable) characters. meaning that a b c a b c b b evaluates to a b

done

Note taken. Thank you for your feedback. I'll remove that
