Good catch! Just updated the article. Ahhhh Angular :) make sure you follow tutorials for Angular 2, as the whole thing changed from 1 to 2. As far as where to begin, I urge you to read through the docs on https://angular.io — but be warned, Google is really pushing TypeScript, so if you’re new to that, there is a slight learning curve (unless you have experience with compiled/strongly typed languages, either way its well documented and is rather straightforward). Good luck!
