   - `watch`: watch an array of reactive sources and auto-refresh the fetch result when they change. Fetch options and URL are watched by default. You can completely ignore reactive sources by using `watch: false`. Together with `immediate: false`, this allows for a fully-manual `useFetch`. (You can [see an example here](/docs/getting-started/data-fetching#watch) of using `watch`.)
