Issues with Haskell tests:

• Reference solution depends on user solution
• No tests done on data types that are not instances of Ord

Fork that fixes both of these.

This probably should be 7kyu.
6kyu usually makes me sit thinking, this was way too easy imo.

Please use code formatting when posting code. See docs on how to format code.

The first letter that repeats might not be the first letter of the word.
For example, the first letter that repeats in content is n. This is the first letter that has more than one occurence in the word.

Also, quotes are just a way to identify strings when displaying them and shouldn't be part your answer.

I feel like even 8 kyu can solve this kata. I thought there were some tweaks to the problem since it is registered as 6 kyu task but nope.

This shouldn't be a 6 and should be regraded to a 7 imho, thanks for the kata tho!

my code works for the most part but I'm stuck with the error 'expected undefined to equal " " ' I don't actually get it. When I change it arounf instead I get 'expected " " to equal undefined'

Way to easy for a 6KYU IMO

That's great! I appreciate it.

Kata creator has being gone for a while, added another example to clarify.

Ahh, I see now. In that case, the description should've used a better example like yours.
Btw, thanks for not resolving the suggestion immediately.

No, that's not either what he meant. In translator you should return t, not a.

v      v  
translator
  ^   ^

While second a appears before second t, in the string of all repeated letters, the first one is t.

"the first character that repeats" and "the character that repeats first" mean exactly the same thing.
You might want to revise the second definition to: "The first character that repeats consecutively"

Yeah, it should be changed somehow. Both descriptions are exactly the same. I've added a suggestion regarding this.

What is that even mean? Object's property by nature doesn't have any order. You access them directly with keys, not with index.
