import { shallowClone, deepClone, deepClonePro } from "fast-clone.js";

// 复杂对象
let obj = {
  num: 0,
  str: '',
  boolean: true,
  unf: undefined,
  nul: null,
  obj: { name: '我是一个对象', id: 1 },
  arr: [0, 1, 2],
  func: function () { console.log('我是一个函数') },
  date: new Date(0),
  reg: new RegExp('/我是一个正则/ig'),
  [Symbol('1')]: 1,
};
Object.defineProperty(obj, 'innumerable', {
  enumerable: false, value: '不可枚举属性' }
);
obj = Object.create(obj, Object.getOwnPropertyDescriptors(obj))
obj.loop = obj    // 设置loop成循环引用的属性
// for shallow clone
let shallowCloneObj = shallowClone(obj);
console.log(shallowCloneObj.obj === obj.obj); // true

// for deep clone, deepClone or deepClonePro are ok, but later is more pro (from lodash)
let deepCloneObj = deepClone(obj);
console.log(deepCloneObj.obj === obj.obj); // false
