title: How can I convert a numerical value to text in JavaScript?
body: <p>I would like to convert a numerical value to a text string. I am opening several windows with the <code>window.open()</code> command and I would like these windows not to be on top of each other.</p>
  
  <p>For that I use the argument "left" and "top" in the windows.open command but these parameters need to be text entities.</p>
  
  <pre><code>for (var i = 0; i &lt; final_number; ++i )
  {
      left_value=50+(50*i);
      list[i]=window.open(url[i],"","height=500,left=left_value,width=1000");
  };
  </code></pre>
  
  <p>When calculating <code>left_value=50+(50*i)</code>, the result is numerical.</p>
  
  <p>The problem is that the <code>window.open()</code> command is expecting a text parameter for <code>left_value</code>.</p>
  
  <p>I thus want to convert left_value from <code>X</code> to <code>"X"</code></p>
