In this challenge, we will be using React's Context API and the useContext Hook to create a dark mode theme switcher for a web page. The challenge involves completing the code in the provided ThemeContext.js file and wrapping the App component with the ContextProvider. Additionally, code needs to be added in both App.js and Card.js using the useContext Hook to implement the functionality. When completed, clicking the 'Dark Mode' button should change the theme color of both the card and the background.
