"npx create-react-app my-app" doesn't work properly

Hi,

I just started with React.

The first time I used "npx create-react-app my-app", it didn't work well -- after I used it, the "react" version I got was "^0.14.0", while the version of "react-dom" was "^18.0.0".

    "react": "^0.14.0",
    "react-dom": "^18.0.0",

I ran "npm start", and "http://localhost:3000/" was a blank page. There were errors, saying something like "react has to be within range".

I searched online with keywords, "what does package.json look like in a react project", and it showed that the version of "react" should be the SAME as that of "react-dom".

So I changed the version of "react" from "^0.14.0" to "^18.0.0":

    "react": "^18.0.0",
    "react-dom": "^18.0.0",

And I also deleted "package-lock.json" and "node_modules"(maybe it was not necessary), reran "npm i". After that I ran "npm start" again, and this time the project started to work properly.

There must be something wrong with the current "create-react-app" app.

I'm not sure anybody would even notice this post. But I hope somebody would.

Thanks.

Regards,
William
