Scala Reactive Programming

Why FP is the best fit for RP

When we conflate RP with FP, we will get the following benefits:

• Composability—we can compose multiple data streams using functional operations so that we can solve even complex problems easily
• Thread safety
• Readability
• Simple, concise, clear, and easy-to-understand code
• Easy-to-write asynchronous, concurrent, and parallel code
• Supports very flexible and easy-to-use operations
• Supports Declarative programming
• Easy to write, more Scalable, highly available, and robust code

In FP, we concentrate on what to do to fulfill a job, whereas in other programming paradigms, such as OOP or imperative programming (IP), we concentrate on how to do. 

Declarative programming gives us the following benefits:

• No side effects ...
