FunctionalTraining

Introducing functional programming to interested and enlightened people.

Running and compiling

In the root directory there is a shell script called sbt it runs the sbt console.

$ ./sbt

To run the exercises simply type test in the sbt console.

> test

To run a single exercise type testOnly ft.<package>.<classnameSpec>

> testOnly ft.higherorder.ComposingExercisesSpec

Completing the exercises

I've kept this quite simple.

There are five packages, covering the areas we will be covering in this course.

Remember:

• The types are the gateway to the solution.
• Avoid mutability at all costs.

Have fun.
