I always forget to inline and return the index I want all together. This makes it much cleaner. 👍

Smart af

At least one of the sample tests should include some duplicate numbers as you say in the kata description there may be duplicates.

Oh!

By definition a tenth of a second will always be one digit (either 0 or 1-9) ;)

First and second point already mentioned below, and still open as issues.

When your test fails, the message doesn't help at all.

(That's because it uses Test.expect, which you should never ever use when comparing for equality. Unless it's for a special reason or you already provide a helpful error...)

I don't understand why this kata's satisfaction is higher than 75%.

There are many flaws:

• There's no sample test cases (what you've put is useless and not relevant)
• When your test fails, the message doesn't help at all. You should, at least, give the user's result and the expected result
• I'm pretty sure I've already solved a very similar kata

Loking nice! like from me)

Nice one.

However, it misses a sample test where the answer is xx.00.

which returns true if the passed string is a palindrome, regardless of capitalisation

Random tests feature uppercase and lowercase characters but the kata description doesn't warn about this.

Solved it with recursion!

As others said, there should be more sample test cases with special characters (thinking about the point in the really last test).
