You're aiming incredibly broad there. StackOverflow is not the best medium to help you build an entire chat application. If you want to see a good example of a chat application on Firebase, have a look at Firechat.

comment How to use .hasChild and retrieve child using Firebase?
The trick to finding a syntax error like that is commenting out blocks of code. If the message persists, the error is not in that code and your try another block. I localized it to this line: $('#messagesDiv').prepend(message.text ": " + message.name);, but will leave it to you to find the actual problem in there.

Have you looked at AngularFire? That is Firebase's own binding for AngularJS and it solves many of the mapping problems, such as the one you seem to have: mapping Firebase's auto-generated keys to array indices (which AngularJS needs).

So you seem to have some code and have a problem making it do what you want. In that case, post the code you have, so we at least have some idea of where you're stuck.

comment how to do lookup query in firebase?
Did you try anything yet? This is probably the method you're looking for: firebase.com/docs/web/api/query/startat.html. Or potentially this one if you're using REST: firebase.com/docs/rest/guide/…

From a quick inspection of your data, it seems that you are nesting. Note that this is not really recommended with Firebase: firebase.com/docs/web/guide/structuring-data.html

"I also find that the ... tutorials are outdated" If you were to provide links to those tutorials, that would be a more constructive statement.

comment Does AngularFire use Firebase's REST API?
I'm pretty sure that my answer below is correct for AngularFire, but was intrigued enough by your documentation quote to post a follow-up quesion: stackoverflow.com/q/28238298/209103
