Scala 2 vs Scala 3 - by examples

This repo was created to show differences between Scala 2 and Scala 3. It is a kind of cheat sheet for devs transitioning form Scala 2 to Scala 3.

There is always example of some functionality in Scala 2 (scala2 folder) and similar example in Scala 3 for comparison with same file name (scala3 folder).

When working with examples in IDEs, open the scala2 and scala3 as separate projects to not confuse scala versions. Each folder can be compiled and run with scala-cli .
