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:
If everything goes well, you will be ready to fetch your first real exercise.
Refer to the Installing Elm page for information about installing elm.
The code you have to write is located inside the
src/ directory of the exercise.
Elm automatically installs packages dependencies the first time you run the tests
so we can start by running the tests from the exercise directory with:
To automatically run tests again when you save changes:
$ elm-test --watch
As you work your way through the tests suite in the file
be sure to remove the
calls from each test until you get them all passing!
This is an exercise to introduce users to using Exercism http://en.wikipedia.org/wiki/%22Hello,_world!%22_program
It is possible to submit an incomplete solution so you can see how others have completed the exercise.
module Tests exposing (tests) import Expect import HelloWorld exposing (helloWorld) import Test exposing (..) tests : Test tests = test "Hello, World!" <| \() -> Expect.equal "Hello, World!" helloWorld
module HelloWorld exposing (helloWorld) helloWorld : String helloWorld = "Hello, World!"
A huge amount can be learned from reading other people’s code. This is why we wanted to give exercism users the option of making their solutions public.
Here are some questions to help you reflect on this solution and learn the most from it.
