Getting started with Scala

Scala mixes object-oriented and functional programming on the JVM.

📖 Key ideas

  1. Scala runs on the Java Virtual Machine and can use any Java library.
  2. It was created by Martin Odersky; Scala 3 is the current major version.
  3. sbt and scala-cli build and run Scala code.
  4. The REPL lets you try expressions line by line.
  5. Apache Spark, Kafka tools and Akka/Pekko are written in Scala.
💡 Real-life example: Like a bilingual speaker: Scala talks Java's language to the JVM and adds its own expressive phrases.
