  <p>I'm encountering this syntax for the first time and am not sure what it's doing:</p>
  
  <pre><code>self.name = _searchString(settings.dataBrowser) || "An unknown browser";
  </code></pre>
  
  <p>What does the or (double pipes) condition do? When would self.name be set to the second value?</p>
