The author's solution as it exists does weird things on them, so for now, no.

Well all data types have a "Limit" to what they can hold or accomplish. there are workarounds for this. but I came back to do this kaya just becuse I though someones comment may be funny. they way they had it writ down I went to view the comment and it said I had not completed this kata so instead of forfeiting to view it I just did it, and now I cant find the comment :/ I think something happened on the server and it gave me someone elses comment and now I cant find it :/ Edit: to the limit thing. that part of the comment was that maybe it should have been left as is so people do some research into the data types and range limits but the isSafeInteger is a nice JS but all it does is check what I just said. I used it myself I use so many languages 99% of them are spoecified the same but others are a little off for whatever purpose

Thanks for this! I've added another Test case for this.
