How can you clone an object and preserve its prototype chain?

function cloneObject(obj) {
  const clone = Object.create(Object.getPrototypeOf(obj));
  Object.getOwnPropertyNames(obj).forEach(prop => {
    const desc = Object.getOwnPropertyDescriptor(obj, prop);
    Object.defineProperty(clone, prop, desc);
  });
  return clone;
}
const obj1 = { name: "John", age: 30 };
const obj2 = cloneObject(obj1);
console.log(obj2.name);
