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 higher-order mapping operator should you use if you want to process operations sequentially and ensure that the order of execution is maintained?

Which higher-order mapping operator should you use if you want to process operations sequentially and ensure that the order of execution is maintained?

The new inner observable is queued for execution.

The new inner observable is merged with the previous one.

The new inner observable cancels the previous one.

When using the `switchMap` operator, what happens when a new inner observable is emitted before the previous one has been completed?

When using the <code>switchMap</code> operator, what happens when a new inner observable is emitted before the previous one has been completed?
