In this chapter, we discussed how Scala supports asynchronous programming using two different APIs—the Scala Futures API and the Scala Async API. We explored both of these APIs with examples.
We also discussed how to use the Scala Future API in the Play Framework and the Akka Toolkit. We will explore these two concepts in detail in the coming chapters.
As we discussed, both of Scala's APIs, Future and Async, support Concurrency well. Unlike Java threads, the Scala Future and Async API support true Parallelism and use the current multi-core processor architecture very well.
Not only the Scala, Akka-based and Play-based applications use the Scala Future API; the source code of Scala, Akka, and Play Framework uses the Scala Future API extensively.
Let's dive into developing Reactive Applications using the Akka Toolkit in Chapter 4, Building Reactive Applications...
