In this exercise, the goal is to replace the index.js file with a index.jsx
using React and React-Dom.
The JS in such file needs to be modified to use React.
Such libraries need to be added as well to the package.json file.
You will also likely need to update the index.html file.
Because JSX is not JS, you need to use Babel (e.g., with react preset)
to transform the JSX code when it is bundled with WebPack.
This means adding the proper module:rules in webpack-config.js.
Then, libraryTarget and library can be removed, as no longer needed.
quizzes.js should be left as it is, with the test cases still working correctly
with Jest.
