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 3.1Watch 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 3.2We can test this at the REPL. Let's run a REPL:
$CMD lein replThen, let's fetch some cocoa and add it to the bowl.
(fetch-ingredient :cocoa 4)
(add :cocoa 3)
