title: Add string to new line in textarea element
body: <p>I want to insert string from a new row to my textarea HTML element.</p>
  
  <p>I have this textarea element:</p>
  
  <pre><code>&lt;textarea id="txtLogs" rows="13" cols="220"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>At some point I add text to the element above:</p>
  
  <pre><code>document.getElementById('txtLogs').value = 'tileloadStart...' + ' ' + layer.get('name') + ' ' + myTime;
  </code></pre>
  
  <p>And after some time again:</p>
  
  <pre><code>document.getElementById('txtLogs').value = 'tileloadEnd...' + ' ' + layer.get('name') + ' ' + myTime;
  </code></pre>
  
  <p>Every time I add a string to the textarea element it is added to the same row while I need the new string to be inserted to new row.</p>
  
  <p>How do I change in my code to add a string to textarea element and display it in the new row?</p>
