We can use it for just about anything. Imperative and functional are two different styles of programming the same things. With functional style, and the set of nice libraries, we can start to decompose the problem into a series of function composition and transformations. When we mix this with concepts and functions like lazy evaluation, pure functions, and parallel streams, we can implement a certain set of concurrency solutions, for example, a lot more effectively than we do with imperative style and shared mutability.
