Note the h function, which is a shorthand for a Vue instance's $createElement method, must be in the scope where the JSX is. Since this method is passed to component render functions as the first argument, in most cases you'd do this:

Vue.component('jsx-example', {
  render (h) { // <-- h must be in scope
    return <div id="foo">bar</div>
  }
})

I just want to know why it is called h and how to remember it :)

It comes from the term "hyperscript", which is commonly used in many virtual-dom implementations. "Hyperscript" itself stands for "script that generates HTML structures" because HTML is the acronym for "hyper-text markup language".
