$('#message") returns a jQuery object, which is 'array-like' (as the
docs say). Arrays start at position zero, so [0] is asking for the
first element in the array (which happens to be the only one).
For example, $('#list li')[2] would give you the 3rd element from that
object. Note that this gives you a standard HTML element, with no
jQuery functions attached. 'value' is a native property.
Essentialy, $('#message')[0] or $('#message').get(0) or
document.getElementById('message') all return exactly the same.
