async.forEachSeries，后跟array.forEach

Question

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？
