title: JavaScript 'if' alternative
body: <p>What does this bit of code represent? I know it's some kind of <code>if</code> alternative syntax...</p>
  <pre><code>pattern.Gotoccurance.score != null ? pattern.Gotoccurance.score : '0'
  </code></pre>
  <p>What's the need for this sort of coding? Is this more efficient or just a shortened version with the same efficiency?</p>
