This kata is a candidate for retirement as it relies on contraints which are not enforced well, and are very difficult to enforce. Please join the discussion and share your opinion on whether this kata should be kept, or retired: https://github.com/codewars/content-issues/issues/167.

My first 4. But it probably too easy for a 4. There's even 7kyus harder than this. Anyway, enjoyed it.

You're welcome.

thank you for help

Expected: '[1,"0","0","0",0]', instead got: '[1,"0",0,0,0]'

i got only 1 false mixed test but i can't see the input so i don't know what the problemis

crazy 4kyu

wont even let me use shift and pop.. darkness

in older javascript versions, Array.prototype.sort() was not guaranteed to be stable.

Yes, it's a Node specific issue, and not really a kata bug.
You assume that elements which are not meant to be moved will stay on their original relative positions, which is not the case with sort in Node 8. sort can, in case of Node 8, reorder elements in any way as long as the final ordering satisfies requirements of your comparer. With input of [2,0,7] it's perfectly fine to get the sorted result of [7,2,0].

Use something like bubble sort but make it sort not-zeros and zeros.

A temporary array/object is a place for you to store values and then stitch them together again.

I assume the kata wants you to implement a sorting algorithm... unless it thinks comparisons should also count as a temporary object, in which case, I am at a loss.

Ranks of approved katas cannot be changed, so please don't complain about that and enjoy the cheap points.

a good kata, but i think it would've been better if it was 5kyu or 6kyu
