转换对象数组的结构

const students = [
  { name: 'Alice', age: 20, scores: { math: 90, english: 85 } },
  { name: 'Bob', age: 22, scores: { math: 88, english: 92 } },
  { name: 'Charlie', age: 21, scores: { math: 95, english: 88 } }
];

const transformedStudents = students.map(student => ({
  name: student.name,
  totalScore: student.scores.math + student.scores.english
}));

console.log(transformedStudents);

const transformedStudents = students.map(student => {
  if (!student || !student.scores) return null;
  return {
    name: student.name,
    totalScore: student.scores.math + student.scores.english
  };
}).filter(student => student !== null);

const transformedStudents = students.map(student => ({
  name: student.name,
  totalScore: student.scores.math + student.scores.english // 确保属性名拼写正确
}));
