-## history
-
 [`history`](https://www.npmjs.com/package/history) is a JavaScript library that lets you easily manage session history in browsers, testing environments, and (soon, via [React Native](https://facebook.github.io/react-native/)) native devices. `history` abstracts away the differences in these different platforms and provides a minimal API that lets you manage the history stack, navigate, confirm navigation, and persist state between sessions. `history` is library-agnostic and may easily be included in any JavaScript project.
