 **Instructions:** Still in the `<Search />` component, add a `onSubmit` handler to the `<form>` tag. When the form is submitted (try clicking the search button), get the value of the state `searchInput` and pass it as a parameter to the `search` prop function that has been provided for you (the `search` prop is passed from the `<Bookings />` component).

 **Instructions:** Add validation to some fields from exercise 24: the first name and last name must not be empty, the email must contain exactly 1 `@` symbol, and at least one `.` symbol after the `@`; the room ID must be a number between 0 and 100. If the fields do not contain correct information when the 'Submit' button is pressed, display a red error message at the top of the page, but do not clear the text already in the field.
 
 **Test:** An invalid input displays an error message after the 'Submit' button is pressed (e.g. an email like `react@com` is invalid). A valid input shows the correct values at the bottom of the page.
 
-**Reflection:** Validating user input is an important part of any application. Without checking the input, you might see unexpected errors when working with the data later.

 #### 28. Date picker
 
-**Instructions:** Add the [js-datepicker](https://www.npmjs.com/package/js-datepicker) package to your project using `npm install`, and import it at the top of the file. Add different IDs to your 'check in date' and 'check out date' `<input>` elements, then create two date pickers using `const checkInPicker = datepicker(YOUR_ID)` (where `YOUR_ID` is the ID you assigned to your check in/check out date elements).

 Packages contain new functions and properties to work with that may not be available in native JavaScript/HTML. Using packages can often save time instead of writing your own functions, as you are importing code that someone else has written. However, this can have downsides; not all packages are high quality, and some may have bugs or may reduce accessibility by recreating native elements (`js-datepicker` recreates HTML's native [datepicker](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/date) element).
 
 Think about some of the code you have written in this lesson - are there any packages available that might have helped you to complete the exercises?
 
 For example, exercise 26 and 27 used validation. Searching npmjs.com for '[validate](https://www.npmjs.com/search?q=validate)' shows multiple packages, such as '[validator](https://www.npmjs.com/package/validator)' and '[Validate](https://www.npmjs.com/package/Validate)'. Open both of these packages in your browser, and consider the following questions:
+
 - Is it clear what this package does? Will it solve my specific problem better than writing my own code?
 - Do I trust that the code in this package is safe to run on my machine? Do other people trust this package? (Hint: look at weekly downloads, last update, dependents, and visit the repository)
 - Is this package accessible? Will it work on all browsers?
