One of the biggest challenges people face when learning Reactive Programming … The difference between event-driven and reactive programming is that event-driven programming revolves around events and reactive programming revolves around data. Reactive Programming is a programming paradigm oriented around data flows and the propagation of change. In this program, it maps the sequence by using the lamda function that doubles every value, then filters the value where x is greater than 4 and finally it reduces the sequence into a sum of all the remaining values. Reactive Programming. Both the libraries are used for reactive programming and handle the stream in similar fashion but the main difference between both of them depends upon the handling of data.
