如何在Flex中克隆对象？

const originalObject = { a: 1, b: 2 };
const clonedObject = Object.assign({}, originalObject);

const originalObject = { a: 1, b: 2 };
const clonedObject = { ...originalObject };

const originalObject = { a: 1, b: 2 };
const clonedObject = JSON.parse(JSON.stringify(originalObject));

function deepClone(obj) {
  if (typeof obj !== 'object' || obj === null) {
    return obj;
  }
  let clone = Array.isArray(obj) ? [] : {};
  for (let key in obj) {
    if (obj.hasOwnProperty(key)) {
      clone[key] = deepClone(obj[key]);
    }
  }
  return clone;
}

const originalObject = { a: 1, b: 2 };
const clonedObject = deepClone(originalObject);
