In Ruby, an array can be returned from a method using the return keyword or by utilizing the implicit return value.
1. Using the return keyword:
def return_array
return [1, 2, 3, 4, 5]
end
puts return_array #=> [1, 2, 3, 4, 5]
2. Using the implicit return value:
def implicit_return_array
[6, 7, 8, 9, 10]
end
puts implicit_return_array #=> [6, 7, 8, 9, 10]
Both methods will successfully return an array as their output. The first method explicitly uses the return keyword while the second method utilizes the implicit return value to return the array.
