Learn Angular’s architecture, creating components, using pipes and directives, and implementing event handling, navigation, and routing with Angular CLI.

Become an AngularJS Developer

In this module, we’ll learn Angular, which is currently among the top JavaScript frameworks. We’ll begin with the basics of an Angular application, including its project structure. Next, we’ll cover how to create components and use pipes and directives in Angular. Lastly, we'll cover event handling, navigation, and routing. By the end, we’ll have learned how to achieve cross-platform high performance with the latest web techniques.

Getting Started with Angular

It handles errors that occur during promise execution.

It chains multiple asynchronous operations.

What is the purpose of the `then` method when working with promises?

What is the purpose of the <code>then</code> method when working with promises?

The timestamp is updated by calling the `setTitle` method directly.

The timestamp is updated using a `setTimeout` function.

The timestamp is updated by emitting events with `observer.next()`.

The timestamp is updated using a synchronous loop.

In the code given below, how is the timestamp updated every two seconds using observables?

```
title$ = new Observable(observer => {
    setInterval(() => {
        observer.next();
    }, 2000);
});

constructor() {
    this.title$.subscribe(this.setTitle);
}
```

In the code given below, how is the timestamp updated every two seconds using observables?
<pre><code>title$ = new Observable(observer =&gt; {
 setInterval(() =&gt; {
 observer.next();
 }, 2000);
});

constructor() {
 this.title$.subscribe(this.setTitle);
}
</code></pre>

By applying a function to each emitted item

How can we use the `map` operator in RxJS to modify data emitted from an observable?


How can we use the <code>map</code> operator in RxJS to modify data emitted from an observable?

It filters data emitted from an observable.

It cancels the current inner observable and switches to a new one.

It performs side effects on data emitted from an observable.

What does the `switchMap` operator do in RxJS?

What does the <code>switchMap</code> operator do in RxJS?

In Angular, why do we need to modify components to subscribe to observables?

In Angular, why do we need to modify components to subscribe to observables?

To automatically subscribe to and unsubscribe from observables

What is the purpose of the `async` pipe in Angular?

What is the purpose of the <code>async</code> pipe in Angular?

Test your understanding of observables and the RxJS library in Angular.
