import { Comp } from "https://deno.land/x/rimbu@0.13.0/common/internal.ts";
const { objectComp } = Comp;
Returns a Comp instance for objects that orders the object keys according to the given keyComp, and then compares the corresponding
values using the given valueComp. Objects are then compared as follows:
starting with the smallest key of either object:
- if only one of the objects has the key, the object with the key is considered to be larger than the other
- if both objects have the key, the values are compared with
valueComp. If the values are not equal, this result is returned.
if the objects have the same keys with the same values, they are considered equal

const c = Comp.objectComp();
console.log(c.compare({ a: 1 }, { a: 1 }))
// => 0
console.log(c.compare({ a: 1 }, { a: 2 }) < 0)
// => true
console.log(c.compare({ b: 5 }, { a: 2 }) < 0)
// => true
console.log(c.compare({ a: 1, b: 2 }, { b: 5 }) < 0)
// => true
console.log(c.compare({ a: 1, b: 2 }, { b: 2, a: 1 }))
