title: Can a for loop increment/decrement by more than one?
body: <p>Are there other ways to increment a <code>for</code> loop in Javascript besides <code>i++</code> and <code>++i</code>? For example, I want to increment by 3 instead of one. </p>
  
  <pre><code>for (var i = 0; i &lt; myVar.length; i+3) {
     //every three
  }
  </code></pre>
