This is the second tutorial in the series about coding an Angular app with a PHP backend. It's based on the XMLHttpRequest interface supported on most browsers and has a plethora of features like the use of RxJS Observable instead of callbacks or promises, typed requests and responses and interceptors. This course introduces PHP developers to AngularJS, the "superheroic MVW framework" from Google. Here is the definition from Wikipedia: In software engineering, dependency injection is a technique whereby one object (or static method) supplies the dependencies of another object. Let's add the getCars() method that subscribers to the data that comes from the service: When we subscribe to observable we expect one of three results: In our case, only the first two results are relevant because the action is not expected to end since the list can be updated at any time with the items that our users add to the list (as you'll see in later tutorials). as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly.
