5,097 PointsExplanation of using "let!"
I did not fully understand how "let!" is being used within the following code:
let!(:todo_list) { todo_list = TodoList.create(title: "Groceries", description: "Grocery list.") }
I believe that we placed the todo_list = inside of a block { } but I am not following let!(:todo_list)

let is lazy-evaluated: it is not evaluated until the first time the method it defines is invoked. You can use let! to force the method's invocation before each example.
