The List
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A list is an abstract data type for an ordered sequence of elements, allowing adding, retrieving, and removing at any position — each element reachable by its index.
Show
A to-do list keeps tasks in order, and the third item is findable by asking for position three.
Watch for
Order and index are the list's whole promise.
