javascript - I don't quite understand about render in vue.js

Question

Why does new Vue need to use render in the future? Isn't render used to replace string templates?

Answer 1

Render can indeed replace string templates. You can use render or template here. Render is highly efficient and template is easy to write, such as the following two forms.

template: '<App/>'
---------------------------
  render:function (h) {
    return h(App)
  },

The purpose of both writing methods is to instantiate an App component under the root element #app.
