按键升序对地图进行排序

const myMap = new Map([
  ['banana', 3],
  ['apple', 1],
  ['orange', 2]
]);

const sortedEntries = [...myMap.entries()].sort((a, b) => a[0].localeCompare(b[0]));

const sortedMap = new Map(sortedEntries);

console.log(sortedMap);
// 输出: Map { 'apple' => 1, 'banana' => 3, 'orange' => 2 }

const myObj = {
  banana: 3,
  apple: 1,
  orange: 2
};

const sortedKeys = Object.keys(myObj).sort();

const sortedObj = sortedKeys.reduce((acc, key) => {
  acc[key] = myObj[key];
  return acc;
}, {});

console.log(sortedObj);
// 输出: { apple: 1, banana: 3, orange: 2 }
