var input = "@ch: THIS IS A BOOK @c:professional-quality display and classified ads using a web interface. You can control the quality of these ads — and accept them later in the production cycle — while still giving your customers a wide range of creative options. At the same time, the process provides an opportunity to cross-sell and upsell your customers to higher value placements by showing them additional options during the creation process. You can even add new categories of advertisements without expending additional resources.";

What if we can assign an action (callback) for each of the 'eat' event ? this way switch/case would be eliminated.
View b
var fsm = StateMachine.create({
initial: 'hungry',
events: [
{ name: 'eat', from: 'hungry', to: 'satisfied', action: 'foo' },
{ name: 'eat', from: 'satisfied', to: 'full', action: 'bar' },
{ name: 'eat', from: 'full', to: 'sick', action: 'coo' },
{ name: 'rest', from: ['hungry', 'satisfied', 'full', 'sick'], to: 'hungry', action: 'doo' },
]});

Weird behavior in chrome's dev tool console
View gist:5251585
I tried to pause the script, then enter following command in the console:
document.getElementById('foo')
The weird part is, sometimes it will show the object state, but some times it will just show the <div> tag, seems it's the result of toString() ?
Is there a way to always get object state in the console ?
