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

A function that consumes values from observables

A data structure that stores values emitted by observables

What is a producer in the context of observables?

What is a producer in the context of observables?

Cold observables produce data outside the observable.

Hot observables create a new execution for each subscriber.

Cold observables share emitted data among subscribers.

Hot observables start emitting items only after subscription.

What distinguishes a cold observable from a hot observable?

What distinguishes a cold observable from a hot observable?

Which type of RxJS subject requires an initial value and always retains the last value to emit to new subscribers?

Which type of RxJS subject requires an initial value and always retains the last value to emit to new subscribers?

An observable emits values 5 and 3. Then a subscription is made. Afterward, the observable emits the value 50. The observer receives only the value 50. What kind of subject is being used in this scenario?
