Summary
In this chapter, I walked you through the most important concepts and vocabulary to understand Multicasting. We started by explaining the role of a Producer, and then we learned the difference between cold and hot Observables; this led us to the definition of Multicasting and Unicasting.
Finally, we explored RxJS Subjects, the different types of Subjects, and the use cases of each.
In the next chapter, we'll practice all of this in a real-world use case. We will learn how to put in place an efficient mechanism of caching in our Recipe app using Multicasting in RxJS and, more specifically, by combining Multicasting operators and Subjects.
