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.
This is an exercise to introduce users to using Exercism http://en.wikipedia.org/wiki/%22Hello,_world!%22_program
Julia 1.0 and 0.7 are the only supported Julia versions on Exercism.
For the most part, the test suites and solutions should be compatible to 0.6, but you will have to change
using Test back to
using Base.Test in the
Note that 0.7 and 1.0 are almost identical, except for deprecation warnings, which have all been removed in 1.0.
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
using Test include("hello-world.jl") @testset "Say Hi!" begin @test hello() == "Hello, World!" end
hello() = "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.
