Is there a particular reason why the <script> element is placed at the bottom of the HTML doc right before the closing </body>? Would the script work the same if it were placed in the <head>?

The reason is that that way you make sure that the HTML DOM is fully loaded before your script runs. Then you don't need to use $(document).ready in jQuery for example.

8,744 PointsThis is to insure that the page is fully loaded before the script runes. Otherwise you might run in to some problems if the script runes before every thing is loaded. In JavaScript that are a few things you can do to avid doing this. One way is to rune check if the page is fully loaded;. Like this: if (document.readyState === "complete") { do something }. You can also use the jquery.ready to check if your page is loaded. And of course you can just put the script tag at the bottom of the page for an easy fix.
