按日期属性对自定义类对象的数组进行排序

const dateArray = [
  { date: '2022-01-01', name: 'John' },
  { date: '2022-01-15', name: 'Jane' },
  { date: '2022-01-30', name: 'Jack' },
  { date: '2022-01-10', name: 'Alice' },
  { date: '2022-01-25', name: 'Bob' },
];

// 比较函数
function compareDates(a, b) {
  const dateA = new Date(a.date);
  const dateB = new Date(b.date);
  return dateA - dateB;
}

// 对数组进行排序
dateArray.sort(compareDates);

const people = [
  { name: 'John', age: 25 },
  { name: 'Jane', age: 30 },
  { name: 'Jack', age: 20 },
  { name: 'Alice', age: 28 },
  { name: 'Bob', age: 22 },
];

// 自定义排序函数
function sortByAge(a, b) {
  return a.age - b.age;
}

// 对数组进行排序
people.sort(sortByAge);
