I noticed this handy package from the react team: https://github.com/facebook/create-react-app/blob/master/packages/eslint-config-react-app/index.js#L24

Looks like they have a list of confusing browser globals. We could enable all the rest to be used without a window. prefix or a /* global Blah */ comment which would be good for ease of use.
