Coding Dojo: Counter App

This is project that can be reimplemented as a code dojo

The idea, is to build a react project from scratch, e.g. using

npx create-react-app counter-app 

or using the skeleton branch in this repo.

Possible tasks

First task is to create a simple counter (button "increase" which show the result). Other tasks are:

1. Decrease Button: Add a button that decreases the count by 1 when clicked.
2. Reset Button: Add a button that resets the count to 0 when clicked.
3. Input Field: Add an input field where users can enter a number. When they click a "Set Count" button, the count should be set to the number they entered.
4. Error Handling: If the user tries to set the count to a non-number or a negative number, show an error message.
5. Save Count: Add a button that saves the current count to a list. Display this list on the page.
6. Local Storage: Use the localStorage API to persist the count and the list of saved counts. When the user refreshes the page, the count and the list should not be lost.
7. Styling: Use CSS or a CSS-in-JS library to style your components and improve the layout of your application.

Please solve the tasks in a test-driven way (TDD).
