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.
Good point, going to think about it again!
Split the tests sir, thank you !
Should probably include more manual tests for varying scenarios:
e.g:
When it is impossible to figure out the entire current hand, solution could be padded with '?' or undefined values.
Also the current manual test case should be split up into separate tests:
it("should return empty list on empty input", ...);and so on.
Also, AFAIK, CoffeeScript had supported the spread operator even before it was in JS. There may be some cases where it doesn't work as expected because of an old version, but if so, your description of the issue is too vague.
Sorry but it is not my responsibility: CW has 1.10.0 only (very few people use CoffeeScript at CW). You can post a bug in "Forum" to ask for a newer version or ... not use the spread operator.
CoffeeScript version doesn't support spread operator due to old language version
