See the first H.

You solved 38 kata's, of which most are white. It's perfectly fine you assess the rank of any kata, but I wonder how you would assess these rather easy kata's after having solved 1000's of them in all colours of difficulty.

ok, but come on, this kata is yellow, not white ... we can expect users to feel comfortable around bigint and some kind of optimisation

We have a good alternative for users like yourself -> kyu 8

Looking at your code, it seems you have array1 and array2 mixed up.
Either this, or I messed up the translation again, but I did not modify any logic when updating to Node 14.

You aren't missing anything. One of the benefits of codewars is that you can see other people's solutions. If you see something you don't understand in someone's solution, you can research it and learn something new. So, you have 3 things to google now.

Oh, thank you for that clarification.

There is a button, but you need to be at least at one level below the kata's level.

I'm learning JavaScript as well. There should be a button to view the solution, though you won't gain any honor after completing the kata. I don't think there is any shame in doing that because it is about learning.

You're welcome :)

In Invalid tests there is a test with an empty string, when you get the first value from it you get undefined

console.log(''[0]) // return undefined

your program should return, "Hello, <name> how are you **doing** today?".

Without the **

This kata is marked as 6 kyu, so it might be too difficult for complete beginners. You can go to kata search page and try to search for something easier. It should be possible to find someting among the easiest kata: the ones marked with white badge, with ranks of 8 kyu or 7 kyu.

Good luck!
