Comment on Union, intersection, difference, and more are coming to JavaScript Sets

  If you need to be able to do unions and you are doing it in javascript, you are being absurdly inefficient compared to setting up a postgres db, but i wont be able to convince you of this because of basically nonsense brainwashing from your corporate conditioning.

    Sets are super useful for all sorts of stuff where you want the datatype to guarantee there is only one instance of a value in the collection. UI components where you are incrementally adding things to a selection is a great example.

    It’s a completely standard feature in many stdlibs and has nothing to with turning JS into a database.
