The reactive programming paradigm is designed to make working with asynchronous events and data streams convenient. 

This course teaches you about the reactive programming paradigm and when to choose it over others. You’ll learn to use new RxJS 7 features to create a recipe book web application that lets users browse and share recipes. In this context, you’ll learn about data streams, error handling, and how to combine streams and transform one data stream into another. You’ll develop an understanding of multicasting and caching streams, how to share data between components, perform bulk operations such as file uploads, and perform real-time updates. Finally, you’ll learn how to test a reactive application. To assess your knowledge, there’s a project, coding challenges, and assessments.

After this course, you’ll be able to determine the utility of the reactive paradigm for any application and have mastery over new RxJS 7 features to create robust reactive applications.

Reactive Programming with Angular and RxJS 7

Which type of observable is used to represent the shared data in the `SharedDataService` class?

Which type of observable is used to represent the shared data in the <code>SharedDataService</code> class?

It updates the recipe details in the `RecipeDetailsComponent`.

It initializes the selected recipe with a default value.

It notifies all subscribers of the last selected recipe.

It handles HTTP requests to fetch recipe data.

What is the purpose of the `updateSelectedRecipe` method in the `SharedDataService` class?

What is the purpose of the <code>updateSelectedRecipe</code> method in the <code>SharedDataService</code> class?

To store the last emitted value and allow late subscribers to receive it

To ensure that data is shared with all components simultaneously

To prevent data from being shared between unrelated components

What is the purpose of using a `BehaviorSubject` in the Angular service for sharing data between components?

What is the purpose of using a <code>BehaviorSubject</code> in the Angular service for sharing data between components?
