[Amir Ebrahimifard]

Hi
What is happen for return value in these 2 codes ?
(Please analysis for me result of these 2 codes)

----------------------------

def test1(name)
puts "Hello"+name
end

def test2(name)
puts "Hello"+name
1+1
end

return_value1 = test1("amir")
puts return_value1

return_value2 = test2("amir")
puts return_value2

If you don't explicitly return anything, ruby returns the value of the
last expression.
