/**
 * A hook to access the redux store's state. This hook takes a selector function
 * as an argument. The selector is called with the store state.
 *
 * This hook takes an optional equality comparison function as the second parameter
 * that allows you to customize the way the selected state is compared to determine
 * whether the component needs to be re-rendered.
 *
 * If you do not want to have to specify the root state type for whenever you use
 * this hook with an inline selector you can use the `TypedUseSelectorHook` interface
 * to create a version of this hook that is properly typed for your root state.
 *
 * @param selector the selector function
 * @param equalityFn the function that will be used to determine equality
 *
 * @returns the selected state
 *
 * @example
 *
 * import React from 'react'
 * import { useSelector } from 'react-redux'
 * import { RootState } from './store'
 *
 * export const CounterComponent = () => {
 *   const counter = useSelector((state: RootState) => state.counter)
