title: Prompt toLowerCase not executing correctly
body: <p>I'm unsure why this isn't executing properly? It's so simple however I can't warp my head around it:</p>
  
  <pre><code>response = prompt(question.toLowerCase());
  </code></pre>
  
  <p>When I insert something into the prompt and I console.log it it seems to come back with uppercase letter that I added when I inserted the value into the prompt.</p>
  
  <p>I want toLowerCase to convert any value into lowercase when submitted.</p>
  
  <p>Any idea why this isn't working?</p>
