Exercism Ruby - Hello World

Alt Text

The classical introductory exercise. Just say "Hello, World!".

"Hello, World!" is the traditional first program for beginning programming in a new language or environment.

The objectives are simple:

  • Write a function that returns the string "Hello, World!".

  • Run the test suite and make sure that it succeeds.

  • Submit your solution and check it at the website.

# Common test data version: 1.1.0 be3ae66
class HelloWorldTest < Minitest::Test
  def test_say_hi
    assert_equal "Hello, World!", HelloWorld.hello
  end
end
Enter fullscreen mode Exit fullscreen mode

My solution is:

class HelloWorld
  def self.hello
    "Hello, World!"
  end
end
Enter fullscreen mode Exit fullscreen mode

I know this time was pretty simple, see you next time!

I'm doing a youtube series about these exercises if you want to follow me, you are welcome, this is the channel juanvqz and this is the exercism playlist
