说我有一个函数，其中async.forEachSeries以array.forEach（）开头。执行的顺序是什么？在array.forEach（）完成之后，async.forEachSeries是否执行？
function(){
array.forEach(){ push into array something}
async.forEachSeries(array){
request.get(array.element)
}
}
我有以下代码并不总是按预期运行，它在大多数时间都运行，但有时在诸如sresult.data.push（...）这样的行上它表示sresult.data是未定义的。我能理解的最可能原因是代码未按顺序运行，因此sresult.data在运行时未定义。有人可以帮忙吗？
function (callback) {
request.get(config.url.sectionMaster + "?parentSectionCode=" + sectionCode, function (err, result) {
// console.log(1)
// console.log(result)
if (err) { return next(err) }
if (result != undefined) {
result = JSON.parse(result.body)
let firstHeading = result.data
if (firstHeading != null) {
firstHeading.forEach(element => {
firstHeadingArray.push({
