通过API获取和存储MailChimp兴趣的Typescript方法

我试图通过一个观众ID查询API来获取Mailchimp的兴趣;我已经创建了下面的代码,可以正确地检索所有内容,但是当我在 forEach loop,我没有得到任何存储。

let obj = {};
let arrays = [];
let newdata;
let textlist;

try {
  const data = await mailchimp.lists.getListInterestCategories(MailChimpAudienceId);
  //console.log(data);
  const categories = data.categories;
  if (!categories.length) {
    console.log(`No categories found in Mail chimp list ${MailChimpAudienceId}`);
  }
  categories.forEach(async element => {
    //console.log(element.id);
    obj[element.title] = element.id;
    arrays.push(element.id);
    newdata = await mailchimp.lists.listInterestCategoryInterests(
      MailChimpAudienceId,
      element.id,
    );
    const interests = newdata.interests;
    interests.forEach(async element => {
      //console.log(element.id, element.name);
      obj[element.name] = element.id;
      arrays.push(element.id);
      textlist += "," + element.id;
    });
    // console.log(interests);
    console.log("obj0>>", obj);
    console.log("arr0>>", arrays);
    console.log("txt0>>", textlist);
  });
  console.log("obj1>>", obj);
  console.log("arr1>>", arrays);
  console.log("txt1>>", textlist);
} catch (e) {
  console.log("err>> ", e);
}
console.log("obj2>>", obj);
console.log("arr2>>", arrays);
console.log("txt2>>", textlist);

如何存储这些值,使数组、对象或文本的值位于二次循环之外?
