title: How to loop through a .txt file and get the values in javascript
body: <p>Basically I have my code set up like this:</p>
  
  <pre><code>function converttxttoArray( filename )
  {
      var reader = (window.XMLHttpRequest != null ) 
                 ? new XMLHttpRequest() 
                 : new ActiveXObject("Microsoft.XMLHTTP");
      reader.open("GET", filename, false );
      reader.send( );
      return reader.responseText.split(/(\r\n|\n)/g); 
  }
  var stop_list = converttxttoArray("../data/stops.txt");
  
    var text = "";
    var i;
    for (i = 0; i &lt; stop_list.length; i++) {
        text += stop_list[i] + "&lt;br&gt;";
    }
  </code></pre>
  
  <p>console.log(text) will just give me:</p>
  
  <pre><code> stop_id,stop_code,stop_name,stop_lat,stop_lon,zone_id,stop_url,location_type,parent_station,platform_code,wheelchair_boarding

  </code></pre>
  
  <p>And here is how the content in my stop.txt file look like:</p>
  
  <pre><code>stop_id,stop_code,stop_name,stop_lat,stop_lon,zone_id,stop_url,location_type,parent_station,platform_code,wheelchair_boarding

  <p>This file is in the cvs style.
  What I want is to get the stop_name, stop_id, stop_code, stop_long.... of each item in the array.</p>
  
  <p><strong>Using javascript Promise api would be great</strong></p>
