//THANKS Rameş Aliyev for the feedback on making this cleaner

// Create instance of People Collection
var people = new People();
// Create new instances of the person models
var person = new Person({name: "Tim", age: 5});
var person2 = new Person({name: "Jill", age: 15});
// Create instances of the views
var personView = new PersonView({
model: person
});
var peopleView = new PeopleView({
collection: people
});
$(document).ready(function(){
// We have to do this stuff in the dom ready
// so that the container objects get built out
// Set el of the views.
personView.el = $('#personContainer');
peopleView.el = $('#peopleContainer');
// Add them to a new instance of the people collection
people.add(person);
people.add(person2);
// Render the views. If you are using the initialize
// method then you do not have to do this step.
personView.render();
//peopleView.render();
// Try on console!
// people.add(new Person({name: 'Rames', age:'23'}));
});

<div id='personContainer' ></div>
<hr>
<div id='peopleContainer' ></div>

</html>

there's a typo, instead of personView.el = $('#personConatiner')
should be: personView.$el = $('#personContainer')
same for the peopleView.$el

I am using the latest versions, jQuery 2.0, Backbone 1.01 etc

Will this work if I am trying it in JS bin? I changed the dependencies so it uses the links that jsbin needs. But the output just kind of displays the top of some box.... and did I mention I'm new to handlebars?

Thanks for this. It allowed me to see that in order to use handlebars you must still include underscore. I'm not sure why that is but I had assumed you swopped out underscore when using handlebar and all sorts of pain resulted.
