[...c].map(n=>n|0) should work.

Do you really need a for? a=>a.map((d,c)=>b[d]?(b.splice(d,0,d),b.splice([...b,0].findIndex((e,g)=>g&&!e),1)):b[d]=d,b=[])&&(b+'').split`,`.map(Number) should work.

@ETHproductions The problem is that map() doesn't iterate at all on undefined values in the array. (That said, I'm pretty sure there's a shorter way than the one I suggested.)

I believe you could do c.map(n=>n|0) rather than (c+'').split`,`.map(Number).

I didn't really test that, but could (c+'').split`,`.map(Number) do the job?
