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

In Ruby, a hash is a collection of key-value pairs. A hash is denoted by a set of curly braces ( {} ) which contains key-value pairs separated by commas. Each value is assigned to a key using a hash rocket ( => ). Calling the hash followed by a key name within brackets grabs the value associated with that key.
This is another way to do this: use the Array#index method. It returns the index of the first occurrence of the element in the array. This returns the index of the first word in the array that contains the letter 'o'. index still iterates over the array, it just returns the value of the element.
Sure, that's perfectly possible and works exactly as in your example.
