adyatan

If I tell you the getter of my lens is x => [x.a, x.b] and ask you what would the setter be? You would say y => ({ a: y[0], b: y[1] }). The point being in some cases the setter can be derived from the getter, but we still explicitly write our setters. Adyatan (hindi for "update") fixes that...

import setter from "adyatan";

let setNameAge = setter(user => [user.name, user.age])
setName(["Devansh", 20], {}) // { name: "Devansh", age: 20 }

Now obviously it works only for cases where you're just changing the structure ie no "logic" involved. Also it's meant to be a toy, YOLO if you want to use it anyways.
