title: Invalid assignment left-hand side, javascript
body: <p>I am sure I am doing something silly here:</p>
  
  <pre><code>var addhtml = '&lt;div id="leftbio" class="left-float"&gt;'
  += '&lt;div id="bioname"&gt;e["screen_name]&lt;/div&gt;'
  += '&lt;div id="biophoto"&gt;&lt;img src="e["profile_image_url"]"/&gt;&lt;/div&gt;'
  += '&lt;div id="biodetails"&gt;e["description"]&lt;/div&gt;'
  += '&lt;/div&gt;';             // invalid assignment left-hand side
  console.log(addhtml);
  </code></pre>
  
  <p>And Netbeans is telling me that <code>invalid assignment left-hand side</code> error.</p>
  
  <p>Whats wrong ?</p>
