please explain the operation of self in a method when self is also the receiver of .each method










0















Consider the code below. self obviously calls the method. But it also receives .each. Shouldn't .each be received by a receiver that is outside the method, such as bar, directly? I am having a difficult time understanding the working logic here.



def find_all
foo =
self.each do |f| #shouldn't I iterate over some enumerable outside method?
if yield(f)
foo << f
end
end
foo
end

bar =

File.open("some-text.txt") bar = s.readlines
my_line = bar.find_all b
puts my_line
