returning an array that contains an array and hash in ruby method?

Question

HI

is it possible to return an array that contains an array and hash from a method in ruby?

i.e

def something
array_new = [another_thing, another_thing_2]
hash_map = get_hash()

return [array_new, hash_map]

end

and to retrieve the array:

some_array, some_hash = something()

thanks

Answer 1

You will only ever be able to return one thing. What you are returning there is an array containing an array and a hash.

Answer 2

Sure, that's perfectly possible and works exactly as in your example.

Answer 3

Ruby methods can be treated as if they return multiple values so you can collect the items in an array or return them as separate objects.

def something
  array_new = Array.new
  hash_new = Hash.new
  return array_new, hash_new
end

a, b = something
a.class # Array
b.class # Hash

c = something
c.class # Array
