HarmonyOS 在ArkTS中map如何转成字符串？

可以参考如下demo:

const map = new Map([
  ['name', 'xxxx'],
  ['age', '18'],
  ['address', 'xxx'],
]);
let jsonObject: Record<string, Object> = {};
map.forEach((value, key) => {
  if (key != undefined && value != undefined) {
    jsonObject[key] = value;
  }
})
let info: string = JSON.stringify(jsonObject);
