The JavaScript Set was introduced to the language in the ES2015 spec, but it has always seemed incomplete. That's about to change with the addition of functions like intersection, union and difference.

    Ah yes, javascript, the database language.

    Jesus fucking christ I am so glad I don’t work in the corporate tech sector anymore.

        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.

        EDIT: Note to self, do not use lemmy while hangry.

        Yep Im wayyyy off base here.

          Why would you need to set up a postgres db…? Unions are a fundamental set theoretic operation that are applicable to all set-like collections. You may as well say “an in memory hash map / list is absurdly inefficient compared to a relational db.” Is it efficient, to you, to spin up a postgres instance to hold a dozen key value pairs?
