Mastering data with 7 new JavaScript Set methods
So, 7 new Set methods are under construction now and I will show you the way they interact with data:
-
how compare 2 Set ?
They're stage 3, but we're getting new methods just for this sort of stuff. You'd be able to do:

-
[AskJS] What Lodash/<insert utility library> functions do you love?
I'm excited for that one :). They are also coming out with intersection, but only for sets.
-
Feedback on my JS library website?
it's highly incompatible with Set helper methods (a stage 3 proposal)

-
Set methods proposal reaches stage 3
I'm also looking forward to map.emplace() and arr.group() and iterator helpers.
-
Is there a concise way to set a key's initial value in a Map object?
Sounds like you want emplace?
-
[AskJS] What are still present issues in contemporary (2022) JavaScript?
There's a proposal to give [emplace to maps](https://github.com/tc39/proposal-upsert).
