Get references to rendered\n elements for imperative operations and third-party integrations.\n---\n\nRefs are a way of getting access to underlying DOM elements in our JSX. While it is true one could just assign an element to a variable, it is more optimal to leave components in the flow of JSX. Refs are assigned at render time but before the elements are connected to the DOM. They come in 2 flavors.\n\n```tsx\n// variable assigned directly by ref\nlet myDiv;\n\n// use onMount or createEffect to read after connected to the DOM\nonMount(() =\u003e console.log(myDiv));\n\n\u003cdiv ref={myDiv} /\u003e\n\n// Or, callback function (called before connected to the DOM)\n\u003cdiv ref={el =\u003e console.log(el)} /\u003e\n```\n\nRefs can also be used on Components. They still need to be attached on the other side.\n\n```tsx\nfunction MyComp(props) {\n\treturn \u003cdiv ref={props.ref} /\u003e\n}\n\nfunction App() {\n\tlet myDiv\n\tonMount(() =\u003e console.log(myDiv.clientWidth))\n\treturn \u003cMyComp ref={myDiv} /\u003e\n}\n```",
