title: while loop prints 1 up and to 10, but gives back 11
body: <p>I am again working in CodeAcademy and I have continued along and now working with while loops. However, I am working a little bit in the scratchpad, and I've noticed something weird to me.
  This code right below this text:</p>
  
  <pre><code>var counter = 1;
  
  while(counter &lt;= 10){
      console.log(counter);
      counter = counter + 1;
  }
  </code></pre>
  
  <p>Gives this as a result.
  Why does 11 pop up at the bottom. It shouldn't be there. Is it counting 0. Or is there some more bitter explanation to this. Would be glad to get some help, thanks :P</p>
  
  <p><strong>Result:</strong></p>
  
  <pre><code>1
  2
  3
  4
  5
  6
  7
  8
  9
  10
  ==&gt; 11 
  </code></pre>
