Loading Javascript Scripts to Browser

[tdan]

When loading Javascript files with <script> tags in your HTML,
do the files load AND run sequentially or does the
HTML simply load the files and run them simultaneously.

If not, how can you force them to run sequentially?

HTML simply load the files and run them simultaneously.

If not, how can you force them to run sequentially?

The execution order is identical to their position in the web page
(top-down), consider:

<script type="text/javascript" src="1.js"></script>
<p>2</p>
<script type="text/javascript" src="3.js"></script>

If you want to change this behaviour, you might work with separate
functions and invoke them at the appropriate time.

OK - so just for clarification, the web page will NOT move onto loading
the next script until it is done executing the previous one. . . that
doesn't seem to be what my web app is doing.

Loading a resource like a script file and executing the script code in a
script file are two different steps. It is certainly possible that a
browser fetches the second file while executing the code in the first file.
