jest-environment-jsdom13

Jest environment using JSDOM 13, which does not support Node 6 (and will therefore not be used in Jest any time soon).

If you need a newer JSDOM than the one that ships with Jest, add this to your package.json:

{
  // …,
  "jest": {
    // …
    "testEnvironment": "jsdom13",
    // …
  },
  // …
}
