Functional Programming In Scala In Javascript. Based on the book "Functional Programming in Scala". I'm solving the exercises in the book using JavaScript, and hopefully learning a few things along the way.
To use locally clone the repo and run the following in the same folder:
npm install
npm start
Then open the generated file "exercises.html". You will see Scala and JavaScript solutions side by side, and all the tests results at the end of the page.
