In your Webpack configuration file, add the Babel loader to the module rules. It should look like this:

module: {
  rules: [
    {
      test: /.js$/, 
      exclude: /node_modules/, 
      use: {
        loader: 'babel-loader',
        options: {
          presets: ['@babel/preset-env']
        }
      }
    }
  ]
}
