#Run this code

#this also

x=[2,6,5,9]
y = x
puts x

puts y

x.pop
puts x
puts
puts y
---------------------------

I understand the first code, y was still pointing to [2,6,5,9]
but isn't the second code similar? shouldn't y still be [2,6,5,9] ?

Or is the method pop an exemption in this case?

Beginner here. Thanks everyone!

In the second snippet x.pop removes the last
element, leaving x=[2,6,5], and y points to
the modified array.
