map和对象复制的妙用

//给每个学生加个学校名称
  const students = [
    {
      id: 1,
      name: 'Abbey',
    },
    {
      id: 2,
      name: 'Patience',
    },
    {
      id: 3,
      name: 'Purvis',
    },
  ];
  const newStudents = students.map(student => {
    return Object.assign({}, student, {
      school: '清华大学',
    });
  });
  console.log(newStudents);
