FP FTW

I love functional programming and types because 1) I am lazy and 2) seek validation.

Functional programming addresses both of my great character traits.

Solving for Laziness

Writing code is easy, testing code is hard. More importantly testing permutations is hard and permutations grow exponentially as the code base gets larger. FP allows us to avoid many of the pitfalls of these permutations through immutability. Which means testing our code isn't nearly as difficult.

Solving for Validation

Is there a better feeling than all your tests passing and feeling confident that it wasn't just your local machine.
