# Goal: block access to Twitter and Facebook while in a Pomodoro
# Note: won't work if you use Chrome, as it maintains an internal (not flushable from CLI) DNS cache. Fuck it.

# This file must be able to touch "/etc/hosts":
# The best way would be to create a group able to modify the "/etc/hosts" file:
# $ sudo addgroup host-manager
# $ sudo chgrp host-manager /etc/hosts

React.js training prerequisites

• Basics of npm: install Node.js and npm, know how to search and install a dependency locally to your project or a tool like create-react-app globally, and how to run scripts (npm start, npm test, npm run whatever…)
• ECMAScript new syntaxes and features we need and use are listed below (you'll benefit knowing them all, I just listed the ones you really use daily and inevitably with React), with links to Kangax tables which lists all those features and many more, with up to date links to Mozilla Developer Network documentation. Also see es6-features.org as a not pretty but efficient and concise introductio
