anonymous functions and stuff

gistfile1.js

var logSomething = function(something) {
	console.log(something);	
};

function do_math(foo, bar, baz) {
	return foo + bar + baz;
};

function do_math_then(foo, bar, baz) {
	var result = foo + bar;

	baz(result);
};

//this would actually return a value
var num1 = do_math(1, 2, 3); //num1 = 6

//this won't return anything, it'll just execute the function you send it
//in this case - an anonymous function
do_math_then(1, 2, function(result) {
	console.log(result); //will log "3"
});

//same as above - but instead of an anonymous function defined inline, it's
//a reference to a function defined elsewhere
do_math_then(1, 2, logSomething); //will log "3"
