title: What does node really mean in Javascript?
body: <p>I always see the word <code>node</code>. As far as I know node means a connecting point... So what do <code>child nodes</code> really mean and what do they do? How are they related to <code>node.js</code>? </p>
  
  <p>Sorry for asking this stupid question. I am really new to AJAX &amp; building a web application.</p>
