 If your application has to handle complicated data, [lodash](https://www.npmjs.com/package/lodash), which we recommended in [part 4](/en/part4/structure_of_backend_application_introduction_to_testing#exercises-4-3-4-7), is a good library to use. If you prefer the functional programming style, you might consider using [ramda](https://ramdajs.com/).
 
-If you are handling times and dates, [date-fns](https://github.com/date-fns/date-fns) offers good tools for that. If you have complex forms in your apps, hava a look would [React Hook Form](https://react-hook-form.com/) be good fit. If your application displays graphs, there are multiple options to choose from. Both [recharts](http://recharts.org/en-US/) and [highcharts](https://github.com/highcharts/highcharts-react) are well-recommended.

 The [Immer](https://github.com/mweststrate/immer) provides immutable implementations of some data structures. The library could be of use when using Redux, since as we [remember](/en/part6/flux_architecture_and_redux#pure-functions-immutable) in part 6, reducers must be pure functions, meaning they must not modify the store's state but instead have to replace it with a new one when a change occurs.
