So, what are we trying to say with this section. Clearly, we have shown examples of how to manipulate lists. Well, what we have done is shown how we can display items on an axis. In that sense, we can see how it is easy to think of asynchronous events and lists of values in the same way, as we are graphically picturing them in the same way. The question is, why do we want to do that? The reason is that this is the mindset the RxJS library wants you to have when you start manipulating and crafting streams in the upcoming chapter.
