Create small AngularJS demo

The idea is to create a little technology demonstrator, in order to showcase the advantages of using AngularJS before my management. What the demo app *does* is *not that important*. It should just demonstrate an AJAX-style interaction, where the end user enters something, the Javascript makes a call to a backend web service, and the corresponding JSON response is rendered into the HTML of the page without a full page refresh. My idea is to make 2 plain web pages, which perform the exact same function, but one of them uses standard Javascript only, and the other uses AngularJS. 1) You must find a public free-of-charge API, which allows for reading structured JSON data. If you know an API you'd like to work with, then that is fine, if not I propose the Github API ([login to view URL]). 2) Using the chosen API, allow the user to enter something, and then display the corresponding result. 3) The two different web pages look the same, and do the same thing. One of them uses browser-built-in Javascript only, and the other webpage uses AngularJS. 4) All Javascript code must be well commented, and clear and straightforward to read. 5) All Javascript code must pass JSLint without warnings – by using the online version at [login to view URL] . 6) The HTML is just basic, simple HTML – a plain page with an input field, a button, and an area where result is shown. Fast delivery is important. I must have this in hand by Friday the 30th of May at the latest. This is really quite open -- my need is just to "showcase AngularJS in the best possible way for a non-techie, contrasting it to plain JS only". If you have a better suggestion then I'm likely to be open to it.
