<!-- Lets say we have some <p>, with simple text
we give it an id -->
<p id="example">Hello, world</p>
<!-- We shall now play around with this element using jQuery -->
<script type="text/javascript">
// The vanilla way of accessing our example p element is
var e = document.getElementById('example');
// Then we would faff about with 'e'
// With jQuery we can get it like...
var ej = $('#example');
// jQuery has its own methods, instead of innerText and
// all those similar properties, we can do
$('#example').text("Goodbye everybody, I've got to go");
// Our example p element text will have changed :)
</script>
