I created a page using React.jsx, and when I typed npm start the page opened index.jsx. However, I deleted index.html and then restored it to " public ", since then my page no longer opens index.jsx, but now it opens index.html (so the result is a white page, which when I write hello < /h1> changes. I would like to know if there is a solution for this problem... My json package if it's useful:

I tried deleting the node_modules file and the package-lock.json file, and then I used npm install to reinstall, but it didn't work
