The format of your output should be an array (for you code above [i, e]). I understood this only by getting the wild guess. I think this is an issue of the description of the task.

OP solved it, closing

I see. Thanks.

It's not random, all the ones your code fail have something in common, it's your job to debug your code, not ours. I already gave you some hints about it. Good luck.

Testing "sayHighHaveCompany", expecting: "say High Have Company"
Expected: "say High Have Company", instead got: "say  HighHave Company
                                                    ^     ^
                                                    |     no space here
                                                    two spaces here

Note: it's not the last word in this case that's missing the space

It fails because it doesn't braeak the last word. but it seems random. On other similar cases doesn't fail.

Expected: "take Next Look Point Number", instead got: "take Next Look PointNumber"

but other:

Testing "longNewBigFeelLook", expecting: "long New Big Feel Look" it pass.

what does your code return for those that fail?

Testing "bigPointCompany", expecting: "big Point Company" Passed

Testing "lastOldFirst", expecting: "last Old First" Passed

Testing "lookHaveAskPoint", expecting: "look Have Ask Point" Passed

Testing "thinkFewFact", expecting: "think Few Fact" Didn't pass

Expected: "think Few Fact", instead got: "think FewFact"

Testing "useHave", expecting: "use Have" Passed

Testing "bigNounsProblemRight", expecting: "big Nouns Problem Right" Passed

I don't see any pattern here, It's just random

Not a kata issue, that's a problem with your code, look for a pattern in the input of those tests your code is failing. See where your code is adding those spaces.

Your function should return an array in javascript.

Please don't post solutions here, why don't you ask under that solution in Solutions instead?

Me neither. I keep passing the 3 sample tests, but none of the submission tests.
