How to fix Webpack React error: Module parse failed: Unexpected token?

Question

Node.js

Webpack installed in React. But when I try to build a dist file by running npm run builder an error comes up:

From package.json:

"scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "builder": "webpack"
  },

From Webpack.config.js:

const path = require('path');

module.exports = {
  mode: 'development',
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js',
  },
};

From index.js:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

ReactDOM.render(<App />,
  document.getElementById('root')
);

Cannot use jsx syntax in js files.
(If you really want to, you can allow it, but I personally am against this.)
Also, you have a bare webpack, and React needs a ton of settings. Either use npm run build(which react-scripts build) or make npm run ejectand edit a real React config.
