title: How to use .subscribe() in node-csvtojson library
body: <p>I am trying to use the csv to csv line function in node-csvtojson (documentation <a href="https://github.com/Keyang/node-csvtojson#convert-to-csv-lines" rel="nofollow noreferrer">here</a>)</p>
  
  <pre><code>csv({output:"line})
      .fromString(my_csv_string)
      .subscribe(csvLine =&gt; {
          console.log(csvLine)
      })
  </code></pre>
  
  <p>But I can't quite understand how I'm supposed to get each independent csv line. In debug mode, it never gets into the <code>subscribe</code> function even though my csv string is properly formed.</p>
  
  <p>As a very simple use case, could someone explain to me how to get an alert box for each line ?</p>
