title: Conflicting boolean values of an empty JavaScript array
body: <p>Can anyone explain why the following two statements both evaluate as <strong>true</strong>?</p>
  
  <pre><code>[] == false
  </code></pre>
  
  <p>and</p>
  
  <pre><code>!![]
  </code></pre>
  
  <p>This question is purely out of curiosity of why this happens and not about how to best test if an array is empty. </p>
