your solution has a bug that incorrectly handles four zeros in sequence
example input data [9, 0, 0, 0, 0, 0, 9]
your code will return [ 9, 0, 9, 0, 0, 0, 0, 0 ]

Hi I checked
your code gives wrong result for
this sequence [9, 0, 0, 0, 9, 1, 2, 0,
1, 0, 1, 0, 3, 0, 0, 1,
9, 0, 0, 0, 0, 0, 0, 9] can you check locally

javascript kata tests output incorrectly expected results and obtained results from the user

you shouldn't post code like that; anyone can see it.

I added the spoiler flag to your comment
