react.default.createContext code example

Example: __WEBPACK_IMPORTED_MODULE_0_react___default.a.createContext is not a function

react-redux v6.0.0 uses the new context api provided by React 
and in order for it work, either you need to downgrade react-redux to v5.x.x 
or upgrade react and react-dom to v16.4 or above

npm update react react-dom
