title: "var variable" returns undefined?
body: <p>When I run "var variable = true;" in chrome console I get "undefined" returned:</p>
  
  <pre><code>&gt; var variable = true;
  undefined
  </code></pre>
  
  <p>But when I run without "var" it returns true:</p>
  
  <pre><code>&gt; variable = true;
  true
  </code></pre>
  
  <p>Why is it returning "undefined" with "var"?</p>
  
  <p>It's confusing cause I expected it would return true.</p>
