Add cocoa

Let's add a new ingredient, namely cocoa.

Warmup

Just to remember how to do it, let's add a new ingredient. Cocoa powder is stored in the pantry and is scoopable. Use the keyword :cocoa to name it.

To navigate to this point in the introduction-to-clojure repo:

$CMD git checkout -f 3.1

Watch me

Luckily, all of the refactoring we did made it very easy to add new ingredients. We just have to add :cocoa to the collections for scooped-ingredients and pantry-ingredients.

To navigate to this point in the introduction-to-clojure repo:

$CMD git checkout -f 3.2

We can test this at the REPL. Let's run a REPL:

$CMD lein repl

Then, let's fetch some cocoa and add it to the bowl.
