I'm having the same problem, the random tests are off by one

Yes thanks you are right I see

This is very inefficient and unnecessary (I did the same when I solved this kata at first!), look at other solutions.

But the task is to check all the elements of the array, right?

Wouldn't this re-run arr.filter(e => e === 1).length for every iteration?

Edit - not sure what's going on there, but you shouldn't have to make sure that the array is all the same. I just use localCompare.

This was more challening than I thought at first.

One thing I don't understand: Why does the original array have to be shallow copied to preserve the order of items that have equal last characters?

OK, I assume it was just a random glitch.

I managed to pass it after "attempting" several times.

Should the last donation be a non positive number (<= 0) John wants us to throw (or raise) an error ~ but your code does not handle this requirement

@pr0ace1, you must use the spoiler tag if you post code (I have added the tag) otherwise eveyone can see it.

Thanks sflicker- I am also getting 'errorExpected' fails when I test my code. Is there any way to see what the errors are? As I can't seem to expand it!

Often print()/console.log() the input works. You may need to click (expand) on the arrow in test case on the output to see this.

hi, my code failed a numebr of tests, but I a unable to see what the failed tests (or the inputs of these failed tests) are. Is there any way for me to see this? Thanks
