I wonder if in this context "Rewriting JavaScript object properties" might be a better way of putting it.

Strangely enough "updating" an Elixir map

%{expenses | groceries: 150, commute: 75}
Enter fullscreen mode Exit fullscreen mode

or an Elm record

{ steve | name = "Wozniak" }
Enter fullscreen mode Exit fullscreen mode

creates an entirely new value as well (because everything is immutable).
