If you carefully watch the trends, then you would know that Kotlin has created not a strong wind but a storm to blow things around it.

The best part is its interoperability with Java. Kotlin, as a language, solves many important problems in Java. On the other hand, Kotlin is also the newest programming language you've heard of (we're guessing you've heard of Kotlin, as this book assumes that you've a little understanding of the language). Why is everyone getting crazy about it? What does reactive programming exactly mean? What are the benefits of reactive programming? And, finally, should we learn it? If yes, then how? So, as a programmer, we are wondering about reactive programming. Even the big IT companies that are often referred to as market giants, such as Google, Facebook, Amazon, Microsoft, and Netflix, are not only supporting and using reactive programming themselves, but they've even started releasing new frameworks for the same. Not only did it get trending, but it has started ruling the software development sector with new blog posts articles every day, and presentations, emerging frameworks and libraries, and more. By the end of the book, you will be able to build real-world applications with reactive user interfaces as well as you'll learn to implement reactive programming paradigms in Android.Ĭhapter 1. A Short Introduction to Reactive Programming This book will also take you one step forward by introducing you to Spring 5 and Spring Boot 2 using Kotlin. You will then be introduced to functional reactive programming and will learn to apply FRP in practical use cases in Kotlin. You will dive into advanced techniques such as manipulating time in data-flow, customizing operators and provider and how to use the concurrency model to control asynchronicity of code and process event handlers effectively. You will begin with the general concepts of Reactive programming and then gradually move on to working with asynchronous data streams.

With this practical book, Kotlin developers will first learn how to view problems in the reactive way, and then build programs that leverage the best features of this exciting new programming paradigm. In today's app-driven era, when programs are asynchronous, and responsiveness is so vital, reactive programming can help you write code that's more reliable, easier to scale, and better-performing.
