title: Javascript upload and parse file on fly
body: <p>Is it possible to upload file using </p>
  
  <pre><code>&lt;input type="file"&gt;
  </code></pre>
  
  <p>and then parse it to javascript array without saving the file on server-side?
  Could you advice any plugin to do it with csv (or any other) file type.</p>
  
  <p>Is it good idea to do things such way without using back-end?</p>
  
  <p>Thanks.</p>
