Dependency Injection with AngularJS
Dependency injection facilitates better testing by allowing us to mock dependencies in testing environments so that we only test one thing at a time. It also enables us to write more maintainable code by decoupling our objects from their implementations. The motivation for using it in AngularJS is to make it easier to transparently load mocked objects in tests. This book is a practical manual to get you started on dependency injection. It will also take you along the road to creating testable and reusable code. Ensuring productivity and stability are the two most important things that you will learn. Dependency Injection with AngularJS will introduce you to AngularJS using a simple sample project. By portraying different ways of developing code modules, it will show you the advantages of dependency injection. This will lead to the ability to create reusable components that can easily be tested. ...

The Problem with Native JavaScript APIs
Many features inspired by popular JavaScript libraries are now available as native JavaScript APIs in today's powerful browsers. While that may seem convenient given all of the JavaScript you need to write, relying on these APIs will only make code maintenance more difficult in the long run. In this report, Nicholas Zakas-consultant and former front-end tech leader at Yahoo! - provides a case study to show how different browsers can develop native APIs for the same specification and still end up with different interpretations. You'll discover how these APIs can tie your code to specific browsers, forcing you to upgrade application logic whenever new browsers and new browser versions are released. ...
