heh, I see now it was little counter intuitive from my perspective.
I just skipped training so I could see if i can do something else instead and I did.
I was dead sure I was right. :\ srry
I am luckier than I think!
ugh, repetio mater studiorum est?
I am now even more confused how the heck did Python code worked?
I leave it for now as it is!
Got it! All is good!

Your Python solution will not work in JavaScript. Your problems are caused exactly by the thing which works in Python, but not in JS. arr[-1] works differently in JS and Python.

No, it's not! It worked. JS.
This just a sick joke.

With your updated code it is:

Your code is using the expression nbPetals % ph.length - 1 to index the array, which can result in -1 when nbPetals is a multiple of 6.

nbPetals % phrasess.length - 1 does not do what you think it does, but you need to take it from here.

I don't get it!

Your code does not correctly calculate the position in the phrases array because the operator precedence is wrong. As a result, the selected index is outside the valid range, causing your function to return undefined instead of a phrase from the list.

Dem, smart

I am not getting this.

When you ask for help, please ask for help and not just post code. Refer to this documentation to debug your code and ask for help efficiently: https://docs.codewars.com/training/troubleshooting/

But it didn't accept the solution and I don't know why I tried even desc.

Don't post solutions in discourse and use the spoiler flag when you post code somewhere.

I have decoder that does this:

Text: a_t__C___5____k_____c______O_______u________K_________A__________r___________!

  H_e__l___l____o_____ ______W_______o________r_________l__________d___________!

can someone help me with the code (Python 3)?

Am I close enough?
Yeah, I took some deep thinking to do this but still not enough I guess.
I don't know what I am doing with this most of the time.

Thanks.
