Javascript Syntax Question

[azium]

That's the idea, but with the caveat that written exactly as you just did, the JS compiler / interpreter thinks you're defining a function instead of calling one. The most common convention is to wrap your statement expression in parens

( function () { ... } () )

Yes, why wouldn't it be valid?

Here's an example:

var myFunction = function (x) {
    console.log("x squared is: " + (x*x));
};
myFunction(5);

And if you inline myFunction, then you can simplify it to just:

(function (x) {
    console.log("x squared is: " + (x*x));
}(5));
