我的代碼看起來(lái)像這樣：(async () => {  try {    const results = await heavyCalculation();    saveResultsToFiles(results);  } catch (e) {    handleError(e);  } finally {    process.exit(0);  }})();const saveResultsToFiles = (results) => {  results.forEach(result => {    (async () => await saveResultFile(result));  })}const saveResultFile = (result) => {  return promiseToPreprocess(result)    .then(processedResult => saveToFile(processedResult))}const promiseToPreprocess = async (result) => {  // this function returns a promise to preprocess the data}const saveToFile = (data) => {  // this function synchronously saves data to a file}我以為這段代碼會(huì)執(zhí)行計(jì)算等待每條結(jié)果被預(yù)處理并保存到文件中然后退出第一步有效，因?yàn)槌绦蛩坪踉诘却敝氐挠?jì)算結(jié)果。但是，似乎 finally 子句是在 forEach 循環(huán)中的承諾解決之前輸入的，導(dǎo)致程序提前退出。我究竟做錯(cuò)了什么？
