 _This package assumes that your code will run in an **ES2015+** environment. If you're using an environment that has limited or no support for ES2015+ such as lower versions of IE then using [core-js](https://github.com/zloirock/core-js) or [@babel/polyfill](https://babeljs.io/docs/en/next/babel-polyfill) will add support for these methods.

-If you are authoring a component which should only be shown under a specific viewport condition, you can leverage the `ifViewportMatches` higher-order component to achieve this requirement.
+This package provides a set of HOCs to author components whose behavior should vary depending on the viewport.
