In this course, you begin with an introduction to Ember.js, a JavaScript framework for building client-side applications.

After that, the course guides you through the steps of building a real application so that you can see how the concepts are applied in practice. You'll learn about the building blocks of Ember one by one, in a way that crushes the allegedly steep learning curve of the framework.

The application will get shinier (and/or more robust) with each chapter. By the end, we will have a decent app, and you'll have a great new skill you can add to your resume.

Developing Robust Ember.js Applications

When we mark something as `@tracked` in a class definition, we tell Ember to recompute any values the property is used in whenever the value of the tracked property updates. If the property is an object, this doesn’t mean that all properties of the tracked object will also be tracked. Those have to be tracked individually.

In our example, `storage`, itself, is tracked, but we don’t change its value. We mutate the `bands` array, which is a property of `storage`, by pushing a new item into it. To make this work, we have to mark the `bands` array as tracked.

To do that, we'll need to install an add-on that provides tracking for all kinds of objects, called `tracked-built-ins`, using the following command:

```shell
ember i tracked-built-ins
```


In this lesson, you’ll learn how to track all kinds of objects using @tracked in an Ember application.
