They didn’t have that?!
The more you learn about JavaScript, the less you understand how the modern web actually functions.
Set functionality was there leveraging object properties this just makes things more concise
Union organizing and intersectionality can only improve things.
This seems like a nice feature. Python has sets like this too, and it’s super useful.
Ah yes, javascript, the database language.
Jesus fucking christ I am so glad I don’t work in the corporate tech sector anymore.
Sets aren’t just for databases
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?
