title: Edit JavaScript code in chrome and reload page
body: <p>Very often I hack and play with the JavaScript code on some website. Many times JavaScript code is secured in a function:</p>
  
  <pre><code>(function(){
      var = ...
      ...
  }());
  </code></pre>
  
  <p>and I cannot access the object defined in that scope.</p>
  
  <p>Moreover such code is only executed once, when the page loads, thus modifying it with the chromium/google-chrome developer console (Sources toool) is useless.</p>
  
  <p>Is there any simple way to live-edit some JavaScript code in a page and reload the page so that it runs the modified code?</p>
