Oh I thought of an other one. In Clojure "objects" are actually maps, which can have non-string keys as well. That means you can destructure maps which have non-string (or, technically, keyword) keys as well:

    (defn foo [{a 1 
                b 2 :as bar}]
      [bar a b])

    (foo {1 "hi" 2 "world" 3 "!"}) ;; => [{1 "hi", 2 "world", 3 "!"} "hi" "world"]  
  

In JS of course you can have Maps with non-string keys, but destructuring doesn't work on them. Plus you have other issues like arrays in JS having equality defined by reference rather than value, making maps less useful overall.
