  module: {
    loaders: [

        test: path.join(__dirname, './js'),
        loader: 'babel-loader',

Answer 1

看下之前的项目，发现有添加stage-2

npm install --save--dev babel-preset-stage-2

var webpack = require('webpack')
var path = require('path')

module.exports = {
  entry: './js/index.js',
  output: {
    path: __dirname,
    filename: 'bundle.js'
  },
  module: {
    loaders: [
      {
        test: path.join(__dirname, './js'),
        loader: 'babel-loader',
        query: {
          presets: ['es2015', 'stage-2']
        }
      }
    ]
  }
}
