title: online Javascript code evaluation tools
body: <p>Do you have a favorite site or homegrown page in your toolbox to help you during development of your Javascript?</p>
  
  <p>Something to help you:</p>
  
  <ul>
  <li>validate</li>
  <li>run</li>
  <li>debug, inspect</li>
  <li>unit test</li>
  </ul>
  
  <p>Looking for somewhere to paste my JS into, click a Run button, and have it evaluate the statements.  This might be for simple snippets for manipulation of numbers, strings, custom objects, etc.</p>
  
  <p><strong>ANSWER</strong> (since no answers before the question was closed actually address the requirements:</p>
  
  <ul>
  <li><a href="http://www.turb0js.com/" rel="nofollow noreferrer">turb0js</a> - lets you step through the code without having to open the browser's console and hunt for the right JavaScript file. Also allows adding an HTML description to the code snippet, and comments from other users. DOM and Console methods don't work.</li>
  <li>jsbin with <a href="http://jsbin.com/blog/protection#comment-1590869196" rel="nofollow noreferrer"><code>// noprotect</code></a> at the beginning of the code, to enable debugging in the browser console</li>
  </ul>
  
  <p>Non-answers: Codepen (can't debug due to its autorun on edit creating a new script); JSFiddle (no direct support for the browser console)</p>
