title: Javascript code run sequence
body: <p>I'm not well familiar with JS, as I mostly develop desktop applications.
  But I do know how to use Firebug ;) 
  I'm wondering how can I find the sequence those much *.js files loaded with HTML being executed and where it starts from? I have no clue how javascript code works.. And I need your tips on it.</p>
  
  <p>I just would like to debug one website page and see how it works (like I do it in MS Studio by stepping into code which everytime starts from the same entry point).</p>
  
  <p>Where do javacript code starts?</p>
  
  <p>I'm sorry if my question sounds foolish..</p>
