>> Every release replaces more keywords with punctuation marks. I can't think of any other examples. Closures get used heavily in JS and arrow functions do make their use quicker and more concise, as well as fixing `this`. Compared to other languages like Scala, OCaml, Elm and Haskell, with symbols for functional combination and pipelining, pattern matching, and whatever you call the thing where you can miss out parameters and use underscores in function bodies in Scala ... JS is relatively light on symbols.
