Can't `npm start` new app, SyntaxError: Unexpected token => on a fresh install

Edit from maintainers: the project requires Node >= 4.0. We’ll fix the CLI to report an error in earlier versions.

• create-react-app hello

• cd hello
• npm start

> hello@0.0.1 start /Users/olivier/Sites/sandbox/hello
> react-scripts start

@olivier-w This requires node >= 4 in order to run since it was uses arrow functions etc…
