+import { onMounted, useTemplateRef } from 'vue'
+
+const div = useTemplateRef('div') // will be bound to the <div> element
+const hello = useTemplateRef('hello') // will be bound to the HelloWorld Component
+
+onMounted(() => {
+  console.log(unrefElement(div)) // the <div> element
+  console.log(unrefElement(hello)) // the root element of the HelloWorld Component
+})
+</script>
+

+export type MaybeComputedElementRef<T extends MaybeElement = MaybeElement> =
+  MaybeRefOrGetter<T>
+export type MaybeElement =
+  | HTMLElement
+  | SVGElement
+  | VueInstance

+  | null
+export type UnRefElementReturn<T extends MaybeElement = MaybeElement> =
