I could imagine by destructuring he means e.g. unapply in Scala: https://docs.scala-lang.org/tour/extractor-objects.html

Ah OK its a functional construct, this make sense. I have seen this in my brief exposure to Clojure. Thanks for the examples and links.

Recent JS versions have it too:

    > let {a,b} = {a: 1, b: 2}
    > a
    1
    > b
    2
