They added a new preset that has all the different presets

first run this code in your terminal or CMD

npm install --save-dev @babel/cli @babel/core @babel/preset-env @babel/register babel-loader

change your .babelrc file to this:

{
"presets": ["@babel/preset-env"]
}

finally your webpack.config.js file should look like this.

const path = require("path")

module.exports = {
    entry: './src/index.js',
    output: {
        filename: 'bundle.js',
        path: path.join(__dirname, "/dist")
    }, 
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: {
                    loader: 'babel-loader'
                }
            }
        ]
    }
}

It looks like you still need to install the "babel-loader" dependency. In the console:

npm install -D babel-loader

See the official docs for more information: https://webpack.js.org/loaders/babel-loader/
