   There are new Array APIs that don’t mutate!

   `toReversed`
   `toSorted`
   `toSpliced`
   `with`

   (already in Safari 16 and Node 20+)

      There are new Set methods coming for `intersection`, `difference`, `isSubsetOf`, `union`!

      Not yet available anywhere yet but I am so ready for these 🏆

         ShadowRealm for sandboxed JavaScript execution will be very helpful in WebC too 👍🏻

         @zachleat I always forget those aren’t there already – it’s sort of like having numbers but no arithmetic operations

      @zachleat toSorta feels like they should have dummies of the existing non-mutating ones, for "consistency”. e.g. toSlice(), toConcat(), etc.

         @erikras seems logical to me!

      @zachleat .with() is by far the greatest DX upgrade of that gang.

      Also this is in Cr/Edge 110+, Fx 115+, Deno too. All modern browsers have it.

   @zachleat @smashingconf attending my 360⁰ ES course would likely cause notebook overflow then 😉 delighted you enjoyed the talk. Hit me up if you have any questions, I'll be glad to help!
