title: Iterate without output
body: <p>This may be a dumb question, but when I try to iterate using while, unless I output the var, it crashes. I simply what to use the while loop without outputting the count </p>
  
  <p>This works, but not what I want:</p>
  
  <pre><code>  - var n = 0
                while n &lt; 4 
                      li= n++
  </code></pre>
  
  <p>This is what I want:</p>
  
  <pre><code>  - var n = 0
                while n &lt; 4 
                      li 
                      n++
  </code></pre>
