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.

Which operator should you use when you want to emit the last emitted values from multiple observables whenever any of them emits a value?

Which operator should you use when you want to emit the last emitted values from multiple observables whenever any of them emits a value?

It requires an initial value to be provided during creation.

 It emits an error if any subscriber is late to the game.

It can emit values asynchronously without subscription.
