【代码优化Tip】关于结构

1、优化前

    values.username = values.firstName + ' ' + values.lastName;
    const params = {
      ...values,
      username: values.firstName + ' ' + values.lastName,
      firstName: undefined,
      lastName: undefined,
    };

2、优化后

  const { firstName, lastName, ...rest } = values;
  const params = {
    ...rest,
    username: `${firstName} ${lastName}`,
  };
