Bang bang into the room
You previously used {{ }} from the rlang package in a function definition to pass an unquoted column name to group_by(). This can also be done within summarize(). In this exercise, you'll work with !! and enquo(), but similar code could also be written to use {{ }}. You'll come back to that in the next lesson.
