title: Simple JavaScript IDE
body: <p>I am brand new to JavaScript and I would like practice my skills using a simple windows based IDE. While learning I do not want to use any CSS or HTML. I would like if possible to have colour single stepping, highlighting and syntax checking. </p>
  
  <p>So for example you could type in your function(s), call it and receive the result</p>
  
  <pre><code>function squareNumber(x) {
    return x*x;
  }
  
  squareNumber(5)
  
  25
  </code></pre>
  
  <p>I would like something better than the Internet Explorer console.</p>
