417* A progressively enhanced HTML [`<form>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form)
418* that submits data to actions via [`fetch`](https://developer.mozilla.org/en-US/docs/Web/API/fetch),
419* activating pending states in {@link useNavigation} which enables advanced
420* user interfaces beyond a basic HTML [`<form>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form).
421* After a form's `action` completes, all data on the page is automatically
422* revalidated to keep the UI in sync with the data.
423*
424* Because it uses the HTML form API, server rendered pages are interactive at a
425* basic level before JavaScript loads. Instead of React Router managing the
426* submission, the browser manages the submission as well as the pending states
427* (like the spinning favicon). After JavaScript loads, React Router takes over
428* enabling web application user experiences.
429*
430* `Form` is most useful for submissions that should also change the URL or
431* otherwise add an entry to the browser history stack. For forms that shouldn't
432* manipulate the browser [`History`](https://developer.mozilla.org/en-US/docs/Web/API/History)

645* Returns a tuple of the current URL's [`URLSearchParams`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams)
646* and a function to update them. Setting the search params causes a navigation.
647*
648* ```tsx
649* import { useSearchParams } from "react-router";
650*
651* export function SomeComponent() {
652*   const [searchParams, setSearchParams] = useSearchParams();
653*   // ...
654* }
655* ```
656*
657* ### `setSearchParams` function
658*
659* The second element of the tuple is a function that can be used to update the
660* search params. It accepts the same types as `defaultInit` and will cause a
661* navigation to the new URL.
662*
663* ```tsx
664* let [searchParams, setSearchParams] = useSearchParams();
665*
666* // a search param string
667* setSearchParams("?tab=1");
668*
669* // a shorthand object
670* setSearchParams({ tab: "1" });
671*
672* // object keys can be arrays for multiple values on the key
673* setSearchParams({ brand: ["nike", "reebok"] });
674*
675* // an array of tuples
676* setSearchParams([["tab", "1"]]);
677*
678* // a `URLSearchParams` object
679* setSearchParams(new URLSearchParams("?tab=1"));
680* ```
681*
682* It also supports a function callback like React's
683* [`setState`](https://react.dev/reference/react/useState#setstate):
684*
685* ```tsx
686* setSearchParams((searchParams) => {
687*   searchParams.set("tab", "2");
688*   return searchParams;
689* });
690* ```
691*
692* <docs-warning>The function callback version of `setSearchParams` does not support
693* the [queueing](https://react.dev/reference/react/useState#setstate-parameters)
694* logic that React's `setState` implements.  Multiple calls to `setSearchParams`
695* in the same tick will not build on the prior value.  If you need this behavior,
696* you can use `setState` manually.</docs-warning>
697*
698* ### Notes
699*
700* Note that `searchParams` is a stable reference, so you can reliably use it
701* as a dependency in React's [`useEffect`](https://react.dev/reference/react/useEffect)
702* hooks.
703*
704* ```tsx
705* useEffect(() => {
706*   console.log(searchParams.get("tab"));
707* }, [searchParams]);
708* ```
709*
710* However, this also means it's mutable. If you change the object without
711* calling `setSearchParams`, its values will change between renders if some
712* other state causes the component to re-render and URL will not reflect the
713* values.
714*
715* @public
716* @category Hooks
717* @param defaultInit
718* You can initialize the search params with a default value, though it **will
719* not** change the URL on the first render.
720*
721* ```tsx
722* // a search param string
723* useSearchParams("?tab=1");
724*
725* // a shorthand object
726* useSearchParams({ tab: "1" });
727*
728* // object keys can be arrays for multiple values on the key
729* useSearchParams({ brand: ["nike", "reebok"] });
730*
731* // an array of tuples
732* useSearchParams([["tab", "1"]]);
733*
734* // a `URLSearchParams` object
735* useSearchParams(new URLSearchParams("?tab=1"));
