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, after which we learned the difference between cold and hot Observables, leading us to the definition of multicasting and unicasting. Then, we explored RxJS subjects, the different types of subjects, and the use cases of each before introducing multicasting operators in RxJS.
In the next chapter, we’ll practice all of this in a real-world use case. We will learn how to put an efficient mechanism of caching in place in our Recipe app by using multicasting in RxJS and, more specifically, by combining multicasting operators and subjects.
