title: How does the Javascript '>' operator compare characters with a space?
body: <p>I am trying to understand this expression:</p>
  
  <pre><code>((ch = stream.getChar()) &gt; ' ')
  </code></pre>
  
  <p>Here, <code>getChar()</code> gets a character. How does this greater-than comparision operator check if any char is greater than an empty space?</p>
  
  <p>Is this possible?</p>
