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.
Go through the setup instructions for ECMAScript to install the necessary dependencies:
http://exercism.io/languages/ecmascript
Install assignment dependencies:
$ npm install
Execute the tests with:
$ npm test
In the test suites all tests but the first have been skipped.
Once you get a test passing, you can enable the next one by
changing xtest
to test
.
This is an exercise to introduce users to using Exercism http://en.wikipedia.org/wiki/%22Hello,_world!%22_program
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
import HelloWorld from './hello-world';
describe('Hello World', () => {
const greeter = new HelloWorld();
test('says hello', () => {
expect(greeter.hello()).toEqual('Hello, World!');
});
});
//jshint esversion:6
//
// This is only a SKELETON file for the 'Hello World' exercise. It's been provided as a
// convenience to get you started writing code faster.
//
class HelloWorld {
hello() {
return "Hello, World!";
}
}
export default HelloWorld;
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.
Level up your programming skills with 3,450 exercises across 52 languages, and insightful discussion with our volunteer team of welcoming mentors. Exercism is 100% free forever.
