About Scala

Scala is a statically typed language that mixes object-oriented and functional programming, with immutable collections and a derivation system for giving custom types new capabilities. It runs on the JVM, and Scala.js lets it target the web. The language is meant to scale from small scripts to large multiplatform applications.

The latest release and LTS release is 3.9.0, and older releases, including Scala 2, stay available. An online playground, a tour and the Scala 3 book help newcomers get started.

Strengths

  • Combines functional and object-oriented styles
  • Runs on the JVM with access to Java libraries
  • Scala.js targets the web
  • Online playground and extensive documentation

Limitations

  • Migrating from Scala 2 to Scala 3 can take work
  • Steeper learning curve than many JVM languages

Alternatives to Scala

Compare all

Software that can replace Scala for an important use case, and what changes if you switch.

  • Kotlin

    A concise, multiplatform programming language from JetBrains for backend, Android, web and desktop apps.

    Kotlin is another JVM language, with concise syntax, null safety and multiplatform targets including Android, web and native. Its best tooling is tied to JetBrains IDEs.

  • OCaml

    A functional programming language with a strong static type system and a native-code compiler.

    OCaml offers functional programming with a strong static type system and a native-code compiler instead of the JVM. It loses direct access to Java libraries and has a smaller ecosystem.
