Q about function definition syntax

[Diogenes]

Hi all,

I had a look at sIFR.js code after parsing it and I have a question
about function syntax. For example

var f=function(){
// statements here
}();


What is the purpose if the second set of parentheses following the
closing brace? Is the intention to execute the function immediately
after it has been defined?

Most functions in sIFR.js do not have this syntax, but a few do.

Thanks in advance for your help.

Cheers
Jim

}();

Yes, the intention is to assign the function *result* to `f'. The anonymous
function here may be a factory; only the "// statements here" will tell.

Thanks PE,

I did a search in this newsgroup for 'function' afterwards
(Doh!) and found much the same info, but you said it best.

Cheers
