FWIW, it's a bit off-topic, but regarding your code where you're
defining and then calling a function:
function(parameter) {
// ...
}(localVariable)
To ensure that that works reliably across implementations, you'll want
to wrap the function expression in parentheses:
(function(parameter) {
// ...
})(localVariable)
I don't remember my source for the information, but I remember that I
trusted the source. It seems to me your version _should_ work
according to the spec, and I know it does for other things, but I
think some significant implementation has an issue with generating the
call without clarifying it as with the parens above.
Happy coding,
