ES6 clone object

Shallow clone: ​​Only the value of the original object itself can be cloned, not its inherited values

function clone(origin) {
  return Object.assign({}, origin);
}

Deep clone: ​​clone the object's own value and the integrated value

function clone(origin) {
  let originProto = Object.getPrototypeOf(origin);
  return Object.assign(Object.create(originProto), origin);
}
