console.log(req.method);
const userModel = new User(req.body)
const dbBack = await userModel.save()
delete dbBack.password
const user = dbBack.toJSON()
console.log(dbBack);
console.log(user);
delete user.password
console.log(user);
res.status(201).json(user)
}
老师这里为什么需要toJSON我试了一下typeof dbBack是个object但却使用delete不掉里面的key

toJSON前后分别打印下这三个看看结果
console.log(Object.isExtensible(person));
console.log(Object.isSealed(person));
console.log(Object.isFrozen(person));
