The more expressive language
Scala 3 is unrivalled in terms of language expressiveness. The tools the language provides you with have a clear and easy-to-understand purpose. You will learn how to leverage them to write clean and short code that will do the exact work you need it to do.
Safer and cleaner modelling
Scala’s powerful type system was enhanced in the new version of the language. Now it is as intuitive and easy to use as it can get. It allows for safer and more scalable modelling of your domain. Most importantly, the developers working on the model don’t need to be experts in the internal workings of the compiler and type system.
Easy migration with strong guarantees
A tremendous amount of work has been put into our compatibility guarantees. In Scala 3, you can update the language version without fear. The migration from Scala 2 to Scala 3 is also intended to be gradual and painless, thanks to advanced cooperation between language versions.
