在道具分配中使用扩展运算符时，React Native接收错误：“在此环境中，assign的目标必须是对象

Question

I'm currently using React with Redux and when I run the following:

const mapStateToProps = state => {
  const employees = _.map(state.employees, (val, uid) => {
    return { ...val, uid };
  });

I get the error stated above which seems to be targeting "...val" in the return method. I'm basically trying to pull all the information I had from Firebase and returning it in the variable "employees." Any help would be appreciated, thanks!

I think the issue is the typeof val isn't an object (either an array[] or an object {}). You can just use return {val, uid}
