Object Descriptors & Property Flags

What object cloning pattern does this code demonstrate?

const original = {
  get value() { return this._value; },
  set value(v) { this._value = v; }
};

const descriptors = Object.getOwnPropertyDescriptors(original);
const clone = Object.defineProperties({}, descriptors);

original.value = 10;
clone.value = 20;

console.log(original.value, clone.value);

Complete property descriptor cloning
This code demonstrates complete property descriptor cloning: 1) It uses getOwnPropertyDescriptors() to get all property descriptors from the original object, 2) It then uses defineProperties() to apply these exact descriptors to a new object, 3) This correctly clones accessor properties with their getters and setters, 4) The clone maintains the same property behavior but with independent state, 5) This approach preserves all property attributes (enumerable, configurable, etc.), 6) It's superior to Object.assign() which doesn't preserve accessors or other property attributes, 7) This pattern is essential for proper deep cloning of objects with custom property behaviors.
