We will learn more about Scala.Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. Scala smoothly integrates features of object-oriented and functional languages, enabling developers to be more productive while retaining full interoperability with Java and taking advantage of modern multicore hardware. Scala makes it easy to avoid shared state, so that computation can be readily distributed across cores on a multicore server, and across servers in a datacenter. This makes Scala an especially good match for modern multicore CPUs and distributed cloud-computing workloads that require concurrency and parallelism.Thanks to its type inference and other features, Scala is a succinct language, typically enabling developers to reduce the size of source code by at least a factor of 2 or 3 compared to Java. Scala is bundled with a rich set of developer tools, resulting in productivity comparable to languages like Ruby or Python, while retaining the performance advantages of Java.
