3,512 PointsHow should you decide upon a name for the "task" in "for task in todo"?
I tested out "for bananas in todo { print(bananas) }" and that worked as well. What's the thinking behind picking an appropriate name for that string?

Treehouse TeacherHi there! In Swift (and really many other languages) the first part of a for ... in
type loop is a variable name. Here are some other appropriate examples:
for fish in fishbowl
for fruit in fruitBasket
for book in bookShelf
The first word of all of these will be the variable name for the individual item we're looking at right then. He could have also used for action in todo
, for item in todo
, or any other name that makes sense in terms of the individual in relation to the group as a whole.
Hope this helps!
