Also, duplicate.

Addition has been done; changing a boolean to a string has been done. Combining them does not make a novel kata.

Also, no random tests.

Test coverage is glaringly incomplete. "Try again" is never even checked.

There are lots of Docs available on publishing ( your first ) kata. Read them. Also read test suites on kata you solved. Not all of them will be prefect, but you'll recognise the bad examples soon enough, and there will be plenty good examples.

Ask for reviews of your kata while still in Draft on Discord#reviewing. You can ask if ideas are new on Discord#kata-ideas; that might save you a lot of time authoring something that will be retired as duplicate.

There is an incorrect JS language version ( with some Python code ).

Very few tests!

this was my first kata. I apologize for the mistakes

Kata is not good.

1. In the beginning of description:

   Given a string, replace all vowels (a, e, i, o, u) with 0...

   But then at the last paragraph:

   Vowels (a, e, i, o, u, A, E, I, O, U) should be replaced by 0...

   So, which is the correct lists of vowels?

2. No sample tests

3. No random tests

1. No sample tests
2. No random tests
3. You shouldn't use rounding to work around float inaccuracy, use approximate equality instead

Nice friendship here

thank you!

Nice Kata
