You should be able to do this without JavaScript by using streaming.

Well, it's just that: an example.  To be fair, the documentation is in dire

But as you can indeed see from my example (or trying it out yourself) it
works not only on YAML strings but also IO objects.

speak of an optimization - it's more like a habit for me.
