Your Project

The best way to learn how to program is to actually program. Throughout this book, you will be programming a complete Chrome extension. A Chrome extension is a program that enhances (or extends) the functionality of the Chrome web browser. The extension we will be building together will ask a user for a name and phone number, then change all the images in the user’s Facebook newsfeed to kittens or puppies, based on the user’s location (as determined by the phone number). This extension (which we call kittenbook) might not be particularly useful, but it will be fun to build, and it will help you learn a lot of important programming concepts along the way.
