What's Next

You now know the core of Scala. Here are natural next steps:

• Scala 3 — explore the new given/using syntax, union types, and improved pattern matching.
• Apache Spark — the most popular big-data processing engine is written in Scala. Learn DataFrames, RDDs, and Spark SQL.
• Akka / Pekko — actor-based concurrency for building distributed, fault-tolerant systems.
• Cats / ZIO — functional programming libraries for type-safe, composable effects.
• Scala.js — compile Scala to JavaScript for frontend development.

Resources

• Scala Official Documentation — the official language guide and API reference.
• Scala Exercises — interactive exercises covering the standard library and key libraries.
• Programming in Scala by Martin Odersky — the definitive book on Scala.
