Do you know that feeling when you find a tool that you need right at the time you need it? This happened to me when I discovered Scala Exercises. I already knew Scala, but was looking for examples of usage of functional programming libraries like cats or doobie, shapeless for type level programming. Scala Exercises are like interactive documentation with lots of examples, where you can directly test your intuitions and understanding of the library. There is no need to setup anything locally, everything happens on the internet, so starting with it is immediate. Have a look at Scala Exercises. You may also be interested in checking out the website of the authors 47 degrees. They are very active in Scala community and it is worth checking their latest activity.

What works for me best when learning is to get a small project and start coding. Sometimes I like to start from a small existing project and play around it, change some things. It is good for me to learn grammar, see what already exists in the language libraries. I like Scala Koans for its coverage of all topics and similarity to other language approaches - there are koans for other languages too! The setup is really straightforward and quickly you can start going through the language features. I would be very interested in hearing from people who never programmed if approach like Scala Koans gives enough introduction to programming. For sure it is a good exercise for people who already programmed and would like to get familiar with a new syntax and concepts. You can find Scala Ko...
