  <h1>JSFuck []()!+</h1>
  
  <p>JSFuck is an esoteric and educational programming style based on the
  atomic parts of JavaScript. It uses only six different characters to
  write and execute code.</p>
  
  <p>It does not depend on a browser, so you can even run it on Node.js.</p>

  <input id="input" type="text" value="alert(1)"/> 
  <button id="encode" type="text">Encode</button>
  
  <div class="checkbox">
    <input id="eval" type="checkbox" checked />
    <label for="eval">Eval Source</label>
  </div>
  
  <textarea id="output"></textarea>
  <div id="stats"></div>
