["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) 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. ## Getting Started For installation and learning resources, refer to the [exercism help page](http://exercism.io/languages/reasonml). ## Building and testing You will need the node package manager (npm) installed - download from [here](https://www.npmjs.com/get-npm) There is one time setup for each exercise, which may take a few minutes: ``` npm install ``` Open two shells, and in the first, start the build process. ``` npm start ``` In the second, start the tests running. ``` npm test ``` As you edit the code, the two processes will continually rebuild and rerun the tests.
