Scala

Scalable Language. It interops seamlessly with Java.

When to Use

• Big Data Distributed Processing: Apache Spark, Apache Flink, and large-scale data engineering pipelines.
• High-Concurrency Reactive Systems: Building resilient distributed services with Akka/Pekko actors or Cats Effect/ZIO.
• Type-Level & Purely Functional Programming: Enforcing compile-time domain guarantees with Scala 3 given/using and opaque types.
• Enterprise JVM Microservices: Leveraging the entire Java ecosystem while utilizing concise, expressive FP idioms.

Quick Start

object Hello extends App {
  println("Hello, World!")
