+ * A hook to access the redux store's state. This hook takes a selector function

+ * that allows you to customize the way the selected state is compared to determine
+ * whether the component needs to be re-rendered.
+ *
+ * @param {Function} selector the selector function
+ * @param {Function=} equalityFn the function that will be used to determine equality
+ *
+ * @returns {any} the selected state
+ *
+ * @example
+ *
+ * import React from 'react'
+ * import { useSelector } from 'react-redux'
+ *
+ * export const CounterComponent = () => {
+ *   const counter = useSelector(state => state.counter)
+ *   return <div>{counter}</div>
