// Hi, if this is your first time editing/reading a Dangerfile, here's a summary:
// It's a JS runtime which helps you provide continuous feedback inside GitHub.
//
// You can see the docs here: http://danger.systems/js/
//
// If you want to test changes Danger, I'd recommend checking out an existing PR
// and then running the `danger pr` command.
//
// You'll need a GitHub token, you can re-use this one:
//
//  0a7d5c3cad9a6dbec2d9 9a5222cf49062a4c1ef7
//
// (Just remove the space)
//
// So, for example:
//
// `DANGER_GITHUB_API_TOKEN=[ENV_ABOVE] yarn danger pr https://github.com/facebook/react/pull/11865
