What does the ‘h’ stand for in Vue’s render method?

If you’ve been working with Vue for a while, you may have come across this way of rendering your app — this is the default in the latest version of the CLI, in main.js:
new Vue({
render: h => h(App)
}).$mount(‘#app’)
Or, if you’re using a render function, possibly to take advantage of JSX:
Vue.component(‘jsx-example’, {
render (h) {
return
