ES6 ... feature support required

[KingMario]

  computed: {
    cartOpened: {
      get () {
        return this._cartOpened
      },
      set (val) {
        this.setCartOpened(val)
      }
    },
    ...mapState({
      cart: state => state.shop.cart,
      products: state => state.shop.products,
      _cartOpened: state => state.shop.cartOpened
    })
  },

The statement ...mapState({ will cause error

@KingMario 这看起来不是一个合法的代码片段。能运行？

@Jianru-Lin 这是 ES6 stage-3 的对象展开运算符 https://github.com/sebmarkbage/ecmascript-rest-spread，可以通过 babel 转译

@KingMario 好的，我研究下
