Object-Oriented Meets Functional

Have the best of both worlds. Construct elegant class hierarchies for maximum code reuse and extensibility, implement their behavior using higher-order functions. Or anything in-between.

SEAMLESS JAVA INTEROP

Scala runs on the JVM, so Java and Scala stacks can be freely mixed for totally seamless integration.

TYPE INFERENCE

So the type system doesn’t feel so static. Don’t work for the type system. Let the type system work for you!

CONCURRENCY & DISTRIBUTION

Use data-parallel operations on collections, use actors for concurrency and distribution, or futures for asynchronous programming.

TRAITS

Combine the flexibility of Java-style interfaces with the power of classes. Think principled multiple-inheritance.

PATTERN MATCHING

Think “switch” on steroids. Match against class hierarchies, sequences, and more.

HIGHER-ORDER FUNCTIONS

Functions are first-class objects. Compose them with guaranteed type safety. Use them anywhere, pass them to anything.

Play Framework makes it easy to build web applications with Java & Scala.

Play is based on a lightweight, stateless, web-friendly architecture.

Built on Akka, Play provides predictable and minimal resource consumption (CPU, memory, threads) for highly-scalable applications.

Scalatra is a simple, accessible and free web micro-framework.

It combines the power of the JVM with the beauty and brevity of Scala, helping you quickly build high-performance web sites and APIs.
