Overview of this book

<p>AngularJS makes web JavaScript web development less painful and more organized – it’s unsurprising that today it’s one of the most popular tools in web development.</p> <p>AngularJS by Example helps you get started with this essential web development framework quickly and easily, guiding you through AngularJS by showing you how to create your own real-world applications. By adopting this approach, you can bridge the gap between learning and doing immediately, as you follow the examples to learn the impressive features of Angular and experience a radically simple–and powerful–approach to web development.</p> <p>You’ll begin by creating a simple Guess the Number game, which will help you get to grips with the core components of Angular, including its MVC architecture, and learn how each part interacts with one another. This will give you a solid foundation of knowledge from which you can begin to build more complex applications, such as a 7 minute workout app and an extended personal trainer app. By creating these applications yourself, you will find out how AngularJS manages client-server interactions and how to effectively utilize directives to develop applications further. You’ll also find information on testing your app with tools such as Jasmine, as well as tips and tricks for some of the most common challenges of developing with AngularJS.</p> <p>AngularJS by Example is a unique web development book that will help you get to grips with AngularJS and explore a powerful solution for developing single page applications.</p>

The Personal Trainer model


No surprises here! The Personal Trainer model itself was defined when we created the 7 Minute Workout app. The two central concepts of workout and exercise hold good for Personal Trainer too.

The only problem with the existing workout model is in the way it has been implemented. Since the model definition is inside WorkoutController (workout.js), we are in no position to reuse the same model for Personal Trainer.

We can either recreate a similar model for Personal Trainer (which does not feel right), or we can refactor the existing code in a way that the model classes (constructor functions) can be shared. Like any sane developer, we will be going with the second option. Let's understand how we can share the model across the application.

Sharing the workout model

JavaScript is a malleable language. You do not need to define any type upfront to use it. We don't have to declare our model to use it. We can very well create the model using the standard object notation...
