javascript - vue 基础问题

Question

const NotFound = { template: '<p>Page not found</p>' }
const Home = { template: '<p>home page</p>' }
const About = { template: '<p>about page</p>' }
const routes = {
  '/': Home,
  '/about': About
}
new Vue({
  el: '#app',
  data: {
    currentRoute: window.location.pathname
  },
  computed: {
    ViewComponent () {
      return routes[this.currentRoute] || NotFound
    }
  },
  render (h) { return h(this.ViewComponent) }
})

ViewComponent 这个是什么？function么？为什么不带function关键字？

Answer 1

ViewComponent ： function() {
      return routes[this.currentRoute] || NotFound
    }

ES6加的对象扩展，增强的对象方法写法。
