title: Add characters to a string in Javascript
body: <p>I need to add in a <strong>For Loop</strong> characters to an empty string. I know that you can use the function concat in Javascript to do concats with strings</p>
  <pre><code>var first_name = &quot;peter&quot;; 
  var last_name = &quot;jones&quot;; 
  var name=first_name.concat(last_name) 
  </code></pre>
  <p>But it doesn't work with my example.
  Any idea of how to do it in another way?</p>
  <p>My code :</p>
  <pre><code>var text =&quot;&quot;;
  for (var member in list) {
    text.concat(list[member]);
  }
  </code></pre>
