No random tests
Node 12. should be enabled
Test.expectshould be replaced withassert.strictEqualTest.expectwithassert.strictEqualThe description should clearly state what the function is supposed to do, even when it's obvious from the function name.
terrible description, no one knows what they have to do
Sorry, I wrote this about 7 years ago and at the time,
String.prototype.repeatwasn't standardized. I've updated the description to better match modern expectations. Hope it helpsThis comment has been hidden.

Needs more tests...
Can anyone explain why it says I failed the test? That's my output:
aaa
ho ho ho
nananananananana
Test Failed: 'a'.repeat(3) should return 'aaa'
Agreed, the responses when testing the code are not very helpful. I'd much prefer seeing an error stating what actually did get returned/logged with my code rather than just the expected output. Basically like most other katas do...
Test should contain 0 repeats... which makes clear how the spec has gaps.
Repeat 0 should return the original. Repeat 1 should return the original and a repeat. If I repeat something, it's said twice.
OR
Repeat 0 returns empty string, Repeat 1 returns the original string.
{ expected: '', actual: 'ho '.repeat(0), msg: ''ho '.repeat(0) should return an empty string' },

FYI The JS code is executed server side. The errors you are seeing in the console is related to the application itself (and most likely the Ace editor plugin, which throws some of its own errors sometimes).
My first attempt didn't work on 'Attempt', it came back with an 'undefined' error. I checked my browser's console (Chrome), and it gave me the error 'cannot call replaced on undefined'. I wasn't trying to call a 'replaced' method anywhere myself. And I've since learned has happened to a few others on CodeWars (unsure whether it was this particular Kata, or otherwise)
I think this will be a cool kata for people to learn a little bit of JS code golf. ;)
