Best way to define and call functions in Javascript
<p>Below is just some sample Javascript that I posted that shows 2 different ways that javascript functions are being defined and called.</p>

<p>Is there a name for these different methods?</p>

<p>Which method is preferred?</p>

<p>The first code block looks really simple, pretty much the same as a procedural PHP function is defined and called.</p>

<p>The second I realize is set up more like a class/namespace it just get's a little confusing for me as I have not studied javascript too much yet.  Am I correct in my thinking that all these functions could be coded in either method as the first or second code blocks and still work? </p>

<p>Sorry if my question is not clear enough, I will revise if needed, thanks for the help/info</p>

<pre><code>initCommentsHelp();

function initCommentsHelp() {
    $('#view-comments-help-a').live('click', function() {
      $('#comments-help').slideToggle("normal");
      return false;
    });
}

<pre><code>Screenshot.Like.Shot.toggle();
