What's confusing about this lesson?
It suggests to use push mutating-op in order to assemble the result,
mutations are evil,
perhaps it can be suggested to use recursion?

Resulting function would be something of this sort:

const traversePosts = async (cid) => {
  // Your code goes here
  postGetResult = await ipfs.dag.get(cid)
  post = postGetResult.value

  return !post.prev ? [cid] : [cid, ... await traversePosts(post.prev)]
}
