title: How to use Promises with PapaParse?
body: <p>PapaParse has an asynch callback function for its API. I was wondering how I can convert it to a promise. For eg:</p>
  
  <pre><code>Papa.parse(fileInput.files[0], {
      complete: function(results) {
          console.log(results);
      }
  });
  </code></pre>
  
  <p>Any help would be appreciated!</p>
