Description
Range#include? iterates over each item in a Range to see if a specified item is there. In contrast, Range#cover? simply compares the target item with the beginning and end points of the Range. In a great majority of cases, this is what is wanted.
For example:
('a'..'z').include?('b')
can be replaced by
('a'..'z').cover?('b')
The raised issue can be ignored in certain cases, like this, where Range#cover? may not provide the desired result.
('a'..'z').cover?('yellow')
