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

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

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

Yes you would. Type irb on the command line for an awesome little scratchpad to try stuff out. Just keep a browser open to the API as well ;)

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
