The function doesn't have a name, so it doesn't pollute the namespace,
and it's great for making functions inline for handlers and
setTimeout() without the burden of having to make up a name that won't
even be referenced.
It's an outgrowth of everything being an object in JavaScript, and
being able to pass any object as a parameter. A function is an object
in JavaScript and can be passed as a parameter.
It's very powerful.
