如何通过两个键来订购JSON对象？

const jsonArray = [
  { key1: "A", key2: 4 },
  { key1: "B", key2: 2 },
  { key1: "A", key2: 3 },
  { key1: "C", key2: 1 },
];

jsonArray.sort((a, b) => {
  if (a.key1 === b.key1) {
    return a.key2 - b.key2;
  } else {
    return a.key1.localeCompare(b.key1);
  }
});

console.log(jsonArray);
