Based on the sound mathematical principle of composing independent units of reliably correct code into computational systems, functional programming offers substantial benefits for the long-term reliability of your applications. The style emphasizes modularity, reusability, and ease of testing and debugging. Because each function in the system is provably correct by design, your code is verifiable, reliable, and free of many common bugs associated with state and scope.
With the foundational concepts securely under your belt, you’ll advance to asynchronous processing concepts, including managing time as state, reducing time dependencies, eager versus lazy processing, Observables, and Promises. Every chapter wraps up with a clear and concise summary, locking in your new knowledge. In the final chapter, you’ll discover a complete application that ties together everything you’ve learned, including clearly explained code. When you’re done reading this invaluable book, you’ll have the FP skills you need to write programs that yield all the benefits of this powerful coding style, including taking your software career to the next level!
