Hello World

Tutorial Exercise
“Hello, World!” will get you writing some Haskell and familiarise yourself with the Exercism workflow. Completing it unlocks the rest of the Haskell Track.


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.

If everything goes well, you will be ready to fetch your first real exercise.

To complete this exercise, you need to implement the hello function.

You will find the type signature for hello already in place, but it is up to you to define the function.
