ually affect application code because computed properties are
almost always observed at the same time as they are fetched. For example, you get
the value of a computed property, put it in DOM (or draw it with D3), and then
observe it so you can update the DOM once the property changes.</p>
<p>If you need to observe a computed property but aren't currently retrieving it,
get it in your <code>init()</code> method.</p>
