// I need to explain this. Soon.

// BAD

function a(){
    console.log(1);
    b();
};

function b(){
    console.log(2);
    setTimeout( c, 1000 );
};

function c(){
    console.log(3);
    console.log( 'done' );
};

a();


// GOOD

var queue = [
    function(){
        console.log(1);
    },
    function(){
        console.log(2);
        setTimeout( next, 1000 );
        return false;
    },
    function(){
        console.log(3);
    }
];

function next(){
    if ( queue.length ) {
        if ( queue.shift()() !== false ) {
            next();
        }
    } else {
        console.log( 'done' );
    }
