/*
Another exercise to repeat classes:

[ x ] 1. Build a form with an input field for an ID (number) and a submit button.
[ x ] 2. Write a class to call the Chuck Norris Jokes API and get the Joke with the given ID.
[ X ] 3. Add another button "Random joke" on your website that asks the API for a random joke.
[ x ] 4. Display the joke as a nice CSS-styled quote on the page.

API:
http://www.icndb.com/api/
