The description still needs to be updated to reflect .toLowerCase() and .replace() having been disabled.

not an issue, unless you can "prove" it: what's the input? Without that, nobody can tell if your code is wrong or the tests. You can reopen with more information if you can prove the problem is in the tests.

Note: it's most likely your code, tho (look at the number of completions)

Please fix random tests
expected [ 'b', 'c', 'd', 'e' ] to have the same ordered members as [ 'a' ]

Don't forget, there is a default value.

https://docs.codewars.com/training/troubleshooting/#print-input

Expected: '['a', 'b', 'c', 'd', 'e']', instead got: '['a', 'b', 'c', 'd', 'e', undefined, undefined, undefined, undefined, undefined]'
104 tests: Passed, 1 test: Fail.
How can i understand where is a problem if i can't see the input of random tests?

same problem

Yes, reset fix the error raised in basic tests

Click Reset, see if the sample tests are different, try again.

Your solution passes all tests, fixed and random. It's rare but it happened to me several times: a valid solution fails on first trial, and then passes repeatedly. Probably some kind of bug...

basic tests 1 failed, but attempt button all tests passed

• No test.assert_equals(first(seq, 0), []);
• It's like that in every language and if n is greater than the length of the array, it should return all the elements of the array, there is no problem with that.

fixed

No problem... you've passed the kata. (???)
