(node:9374) Warning: To load an ES module, set "type": "module"

I just started to learn React today. How do I get rid of that error message on my Console in the Terminal in Visual Studio.

(node: 9374)Warning: To load an ES module,
 set "type": "module" in the package.json or use the .mjs extension. 
/Users/nishihaider/workspace-ui/react-todo-app/src/App.js:1
import React from "react";
import "./App.css";

function App() {
  <>
  return (
  <h1>ToDo</h1>
  );
  </>
}

export default App;

First, install the latest version of Node.js. It has the latest and greatest features.

Second, add the "type": "module" line in your package.json file.

{

  "type": "module"

}

Third, use the --experimental-modules flag when invoking nodejs:

node --experimental-modules app.js

You should be good to go!

An alternative is to avoid adding the "type": "module" line in your package.json file and instead rename your app.js file to app.mjs.

Note that now the require() syntax will stop working.

Here is my approach:

1 - Update package.json like:

  "main": "index.js",
  "type":"module",

2 - use.js when importing, like:

import {isPrime} from './isPrime.js';

3 - here is isPrime.js

export const isPrime ....

You just need to update package.json like this,

{"type": "module"}

It's worked for me, Thanks!
