Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
I meant read these docs: https://docs.codewars.com/training/troubleshooting#post-discourse
As for the link you asked, try this one
You will not find definitions of "positive" and "non-negative" in JS documentation, because these are not JS concepts, but mathematics. "Mathematically speaking" (at least w.r.t. what is, I believe, the most common interpretation), the set of non-negative numbers and positive numbers are not exactly the same, and they differ very slightly (by one element, to be precise).
There is no confirmation of your words in the JS documentation, I ask for a link.

Your code is wrong. Read the docs about how to post code in discourse, please.
non-negative integers is not the same as positive.

Approved
Lua translation!
Your suggestion goes against the current description, won't happen.
Hi, maybe you could add negative integers in the array, and also some corner cases like Infinity or NaN
Fixed examples in the description.
Yes, this is Kotlin.
I assumed that the description of the kata is common to all languages, but I learn that it is necessary to indicate the language
That's in Kotlin, right? Please mention the language next time so it's easier to fix.
Error in examples in task description:
"filterList(ListOf(1, 2, "a", "b", 0, 15)) == [1,0,15]
filterList(ListOf(1, 2, "a", "b", "aasf", "1", "123", 231)) == [1,2,123]"
There are no these errors in the test tasks
Can smbd tell my why that error in my code
class java.lang.Integer cannot be cast to class java.lang.Character (java.lang.Integer and java.lang.Character are in module java.base of loader 'bootstrap')
