Node.js：Array.prototype.sort数组排序的使用

Array.prototype.sort(compareFn?: (a: T, b: T) => number): this;

let list = [1, 3, 4, 2]
// asc 从小到大排序
list.sort((a, b) => {
  return a - b
})
console.log(list);
// [ 1, 2, 3, 4 ]

let list = [1, 3, 4, 2]
// desc 从大到小排序
list.sort((a, b) => {
  return b - a
})
console.log(list);
// [ 4, 3, 2, 1 ]

let list = [
  {
    name: 'Tom',
    age: 12,
  },
  {
    name: 'Jack',
    age: 10,
  },
  {
    name: 'Steve',
    age: 11,
  },
]
list.sort((a, b) => {
  return a.age - b.age
})
console.log(list)
// [
//   { name: 'Jack', age: 10 },
//   { name: 'Steve', age: 11 },
//   { name: 'Tom', age: 12 }
// ]
