Directives and pipes are incredible and often undervalued features of the Angular framework. They allow us to write efficient code, improve application performance, and omit code duplications.

In this course, you will learn about the theory and the working mechanisms of built-in directives and pipes in Angular. You’ll also implement some custom directives and pipes to learn about their real-world application cases. With this course, you will improve your Angular skills and refine your project’s codebase to increase the performance and readability of your code.

Directives and Pipes in Angular

## Objectives

We want to change the user profile card we implemented recently so that it works well with a fully asynchronous way of getting the user data. Below are the specific requirements:

- The user data should be fetched using `UserService`.
- The subscription to `Observable` user data should be in the template when we use `AsyncPipe`.
- Inside the card, the `fullname` pipe should allow us to render the user name and last name.

- Inside the card, the `accountType` pipe should allow us to render the type of account.



## Task
Let’s write the code below:
