Functional reactive programming

Every programming language or technical domain has some kind of pictorial representation to explain certain concepts and make things easier to translate in logical pictorial representations. Similarly, we can express certain reactive concepts in logical pictorial representations. In this book, you will see the use of diagrams to represent functional and reactive concepts and hence it becomes important to have a basic understanding of these diagrams and how you can read them to understand the programming concept they want to showcase. In subsequent sections, we will give a brief introduction to the different types of Logical diagrams. You will get to learn more about concepts like state, side effects, signals, events, and so on in the later half of the chapter. Understanding these concepts is very important because these concepts form smaller elements...
