• Modern JavaScript
• Software Linter

• Files executed on Ubuntu 18.04 LTS using NodeJS 12.11.x
• Allowed editors: vi, vim, emacs, Visual Studio Code
• Mandatory README.md file
• Code should use the js extension
• Code tested using the Jest Testing Framework and command npm run test
• Code analyzed using the linter ESLint along with specific rules provided
• All functions must be exported
• All test and lint need be passed and verifed by running npm run full-test

(in your home directory):

curl -sL https://deb.nodesource.com/setup_12.x -o nodesource_setup.sh
sudo bash nodesource_setup.sh
sudo apt install nodejs -y

$ nodejs -v
v12.11.1
$ npm -v
6.11.3

In your project directory:

• Install Jest using: npm install --save-dev jest
• Install Babel using: npm install --save-dev babel-jest @babel/core @babel/preset-env
• Install ESLint using: npm install --save-dev eslint
