To create a new project with Scala 3

sbt new scala/scala3.g8

and give it a name when asked

$ name [Scala 3 Project Template]: <name>

Then

cd <name>

 

Then with Visual Studio Code, open the new folder, with the name you gave. Run sbt in terminal there and run tasks there, including console for REPL
