Now we are ready to apply everything we’ve learned and design and then build the Blackjack program from scratch to win the Haskell magician competition. This is the only chapter where we will carefully discuss step by step building a program from nothing to fully functional, down to the “main” function. It should allow you to follow the logic and then apply it when building your own, much more complicated projects, as well as follow the more advanced concepts we will be reviewing in the next chapters.
