title: When is while (--i) used?
body: <p>I understand that while loops will continue to run "While something is true"<br>
  But when would I use </p>
  
  <pre><code>while (--i)
  </code></pre>
  
  <p>I understand that this says "while decrements i is true"</p>
  
  <p>I know for sure that my understanding of this statement is incorrect.</p>
  
  <p>I hope someone can give me an example of when this would be used.</p>
  
  <p>I'm thinking that it would be like an if statement that just keeps on happening when the i gets decreased.</p>
