What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-29, confidence not recorded

The Scala 3 compiler (Dotty), along with the Scala 3 standard library and language specification. It compiles Scala 3 source code to JVM bytecode and defines the Scala 3 language.

Use cases

compile scala 3 code
learn the scala programming language
migrate a project from scala 2 to scala 3
build functional programs on the jvm
contribute to the scala compiler
read the scala 3 language specification

When to choose

you are writing or compiling Scala 3 applications
you want the reference implementation of the Scala 3 language
you need the official Scala standard library and language spec

When to avoid

you need a Scala 2-only toolchain (use the Scala 2 compiler)
you want a build tool rather than a compiler (use sbt or mill)
you need a JVM-independent language runtime
