# A {Capybara::Result} represents a collection of {Capybara::Element} on the page. It is possible to interact with this
|
|
# collection similar to an Array because it implements Enumerable and offers the following Array methods through delegation:
|
|
#
|
|
# * []
|
|
# * each()
|
|
# * at()
|
|
# * size()
|
|
# * count()
|
|
# * length()
|
|
# * first()
|
|
# * last()
|
|
# * empty?()
|

# @see Capybara::Element
