You're totally welcome
HTML with AngularJS is very readable, and because you code the event(s)
on the HTML tags all your code also keeps working when you change the structure of your HTML.
Something that is always a bit of a headache with libraries like JQuery where you have to code
against the DOM structure using ID's, classes or a path (and that path can change when you change the HTML structure).
As for curl, it's one of the tools you can use to talk directly to web services. For instance there is also
PostMan for Chrome and as Mac/Windows/Linux app. Or my favourite;
Paw (Mac only). In fact that curl code was generated by Paw so I could show you a working syntax (without having to use Paw).
