Angular with Relaunch

This course will teach you step-by-step how to design and architect large Angular applications. 

You’ll start with the basics: components, pipes, and directives. These are the building blocks of any Angular application, so you will get plenty of hands-on practice with this material. Next, you’ll ramp things up by stepping into modules, routing, and RXJS, where you’ll learn how to declaratively manage data and dive deep into observables.

In the latter half of the course, you’ll cover reactive and template forms (crucial for handling user data), as well as custom validators and setting up authentication with Firebase.

By the end of this course, you'll be able to design large, scalable applications, be able to develop rich interactive components, and you’ll really understand how Angular works under the hood.

Angular: Designing and Architecting Web Applications

We'll start from the basics and work our way up. We'll be stepping away from our project for this example. Once we have a good understanding of RxJS, we'll look at how this ties into our application.

# Terminology

Half the battle of learning RxJS is understanding the terminology. The first term we'll learn is **observable**. According to the dictionary, the word **observe** means to watch something. Therefore, we can conclude that an **observable** is the thing we're watching. 

This leads us to further questions. What are we watching, and why?

Concerning RxJS, an observable is an object. When we create an observable, we're watching an object. What exactly are we watching for? Values! An observable is an object that emits values. It is the *source of values*.

# Creating an observable

Let's create an observable with RxJS. For this example, we'll create an `<input>` element to listen for the `input` event. In Vanilla JavaScript, we would do the following:

```javascript
const input = document.querySelector('input');

input.addEventListener('input', (event) => {
  // Some code here...
});
```

In RxJS, we'll do the following.
