Scala has a similar data structure https://www.scala-lang.org/api/2.13.6/scala/collection/immut.... Something was in the air in 2013.

It’s not a secret that they came from the same zeitgeist but took wildly different approaches, but inspired each other.

I still don’t understand why they’re referred to as persistent vectors rather than immutable vectors, but I digress.

I believe that immutable just means, well, immutable, but persistent means that updates are achieved via structural sharing, so they’re efficient.
