Feature Datepicker

### 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 your booking table component. Add different IDs to your 'check in date' and 'check out date' `` 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).

**Hint:** Read the [js-datepicker usage guide](https://www.npmjs.com/package/js-datepicker#basic-usage)

**Test:**

The date picker appears when you click on the 'check in date' and 'check out date' input elements.

**Reflection:**

Using `js-datepicker` in this exercise allows you to practice installing and working with packages in JavaScript.

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
- 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 project. Are there any packages available that might have helped you to complete the features?

For example, #26 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?
- If I decide to use this package and it breaks, will I know how to fix it or replace it?
