Absolutely none, IMHO. I use a js framework that I wrote to handle the setting of whatever server-side variables I need to have access to.

This results in much cleaner, more organized and lowly-coupled modular code.

You could do something like this in your html:

And then do something like this in your js:

if (registry.myInt === 1) {
    alert(registry.myString);
}
