Do spaces in JS make a difference?

Is:

Code:

<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
try {
var pageTracker = _gat._getTracker("UA-Hide");
pageTracker._trackPageview();
} catch(err) {}</script>

The same as:

Code:

<script type="text/javascript">var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));</script><script type="text/javascript">try {var pageTracker = _gat._getTracker("UA-Hide");pageTracker._trackPageview();} catch(err) {}</script>

Nope. White space makes no difference at all.

just as long as the commands are terminated with a semicolon.

Well, they'll bloat your code =)

If it's compressed code that your looking for, try the YUI compressor. It makes your code pretty much impossible to read, but as long as you have a back-up you're good.
