method
sort

sort()
public
Returns a new array created by sorting self.
Comparisons for the sort will be done using the <=> operator or using an optional code block.
The block must implement a comparison between a and b and return an integer less than 0 when b follows a, 0 when a and b are equivalent, or an integer greater than 0 when a follows b.
The result is not guaranteed to be stable. When the comparison of two elements returns 0, the order of the elements is unpredictable.
a = [ "d", "a", "e", "c", "b" ] a.sort #=> ["a", "b", "c", "d", "e"] a.sort { |x,y| y <=> x } #=> ["e", "d", "c", "b", "a"]
