HTML

<script src="https://unpkg.com/vue@2.3.3"></script>
<div id="app">
</div>

JavaScript

new Vue({
  el: '#app',
      // render is a function defined here as accepting the function h as parameter and returning the h result when evaluated with a template (in here two params: the tag and the value)
  render: h => h('h1', 'Hello')
      // Same but probably easier to understand for most humans who prefer long but straightforward text rather than short but cryptic:
      /*render: function(createElement) {
        return createElement('h1', 'Hello');
      }*/
})
