Execute multiple AJAX requests sequentially

Is there a way to make multiple ajax calls consecutively in vanilla JavaScript, without using jQuery like mentioned in this Stack Overflow post? For example, ensuring that request #2 is only made after request #1 has successfully finished.

Implement a callback function in your code.

xmlhttp.onreadystatechange=function()
{
     if (xmlhttp.readyState==4 && xmlhttp.status==200)
  {
     document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
  }
}
