//this function adds 3 to the number passed in
function addThree(x) {
    return x + 3;
}

//this function takes a function and returns
//a function that runs the function it was passed,
//and then runs that function _again_ on the return
//value of the first call to the function.
//make sense? look at it until it does.
function composed() {
    return function(number) {  // this is a function *definition*, not really a function call!
        return addThree(addThree(number))
    }
}

composed()(4);  // this actually runs whatever_was_returned_from_composed(4);
//what does that return?
