Hello World Npm

A hello world npm module whose real purpose is to experiment a 'modern' (TypeScript / ES6) module declaration and its consumption by various environments, including legacy.

This is an "emo" hello world, in reference to this article: JavaScript Modules: Welcome to My Emo Hellscape.

Usage

npm i --save hello-world-emo
yarn add hello-world-emo

import { hello } from 'hello-world-emo'

hello()           // --> Hello, World :-(
hello('Offirmo')  // --> Hello, Offirmo :-(
