/**
 * Qwik Optimizer marker function.
 *
 * Use `$(...)` to tell Qwik Optimizer to extract the expression in `$(...)` into a lazy-loadable
 * resource referenced by `QRL`.
 *
 * @param expression - Expression which should be lazy loaded
 * @public
 * @see `implicit$FirstArg` for additional `____$(...)` rules.
 *
 * In this example, `$(...)` is used to capture the callback function of `onmousemove` into a
 * lazy-loadable reference. This allows the code to refer to the function without actually
 * loading the function. In this example, the callback function does not get loaded until
 * `mousemove` event fires.
 *
 * ```tsx
 * useOnDocument(
 *   'mousemove',
 *   $((event) => console.log('mousemove', event))
 * );
 * ```
 *
 * In this code, the Qwik Optimizer detects `$(...)` and transforms the code into:
 *
 * ```tsx
 * // FILE: <current file>
 * useOnDocument('mousemove', qrl('./chunk-abc.js', 'onMousemove'));
 *
 * // FILE: chunk-abc.js
 * export const onMousemove = () => console.log('mousemove');
 * ```
 *
 * ## Special Rules
 *
 * The Qwik Optimizer places special rules on functions that can be lazy-loaded.
 *
 * 1. The expression of the `$(expression)` function must be importable by the system.
 * (expression shows up in `import` or has `export`)
 * 2. If inlined function, then all lexically captured values must be:
 *    - importable (vars show up in `import`s or `export`s)
 *    - const (The capturing process differs from JS capturing in that writing to captured
 * variables does not update them, and therefore writes are forbidden. The best practice is that
 * all captured variables are constants.)
 *    - Must be runtime serializable.
 *
 * ```tsx
 *
 * import { createContextId, useContext, useContextProvider } from './use/use-context';
 * import { Resource, useResource$ } from './use/use-resource';
 * import { useSignal } from './use/use-signal';
 *
 * export const greet = () => console.log('greet');
 * function topLevelFn() {}
 *
 * function myCode() {
 *   const store = useStore({});
 *   function localFn() {}
 *   // Valid Examples
 *   $(greet); // greet is importable
 *   $(() => greet()); // greet is importable;
 *   $(() => console.log(store)); // store is serializable.
 *
 *   // Compile time errors
 *   $(topLevelFn); // ERROR: `topLevelFn` not importable
 *   $(() => topLevelFn()); // ERROR: `topLevelFn` not importable
 *
 *   // Runtime errors
 *   $(localFn); // ERROR: `localFn` fails serialization
 *   $(() => localFn()); // ERROR: `localFn` fails serialization
 * }
 *
 * ```

/**
 * The `QRL` type represents a lazy-loadable AND serializable resource.
 *
 * QRL stands for Qwik URL.
 *
 * Use `QRL` when you want to refer to a lazy-loaded resource. `QRL`s are most often used for code
 * (functions) but can also be used for other resources such as `string`s in the case of styles.
 *
 * `QRL` is an opaque token that is generated by the Qwik Optimizer. (Do not rely on any properties
 * in `QRL` as it may change between versions.)
 *
 * ## Creating `QRL` references
 *
 * Creating `QRL` is done using `$(...)` function. `$(...)` is a special marker for the Qwik
 * Optimizer that marks that the code should be extracted into a lazy-loaded symbol.
 *
 * ```tsx
 * useOnDocument(
 *   'mousemove',
 *   $((event) => console.log('mousemove', event))
 * );
 * ```
 *
 * In the above code, the Qwik Optimizer detects `$(...)` and transforms the code as shown below:
 *
 * ```tsx
 * // FILE: <current file>
 * useOnDocument('mousemove', qrl('./chunk-abc.js', 'onMousemove'));
 *
 * // FILE: chunk-abc.js
 * export const onMousemove = () => console.log('mousemove');
 * ```
 *
 * NOTE: `qrl(...)` is a result of Qwik Optimizer transformation. You should never have to invoke
 * this function directly in your application. The `qrl(...)` function should be invoked only after
 * the Qwik Optimizer transformation.
 *
 * ## Using `QRL`s
 *
 * Use `QRL` type in your application when you want to get a lazy-loadable reference to a resource
 * (most likely a function).
 *
 * ```tsx
 * // Example of declaring a custom functions which takes callback as QRL.
 * export function useMyFunction(callback: QRL<() => void>) {
 *   doExtraStuff();
 *   // The callback passed to `onDocument` requires `QRL`.
 *   useOnDocument('mousemove', callback);
 * }
 * ```
 *
 * In the above example, the way to think about the code is that you are not asking for a callback
 * function but rather a reference to a lazy-loadable callback function. Specifically, the function
 * loading should be delayed until it is actually needed. In the above example, the function would
 * not load until after a `mousemove` event on `document` fires.
 *
 * ## Resolving `QRL` references
 *
 * At times it may be necessary to resolve a `QRL` reference to the actual value. This can be
 * performed using `QRL.resolve(..)` function.
 *
 * ```tsx
 * // Assume you have QRL reference to a greet function
 * const lazyGreet: QRL<() => void> = $(() => console.log('Hello World!'));
 *
 * // Use `qrlImport` to load / resolve the reference.
 * const greet: () => void = await lazyGreet.resolve();
 *
 * //  Invoke it
 * greet();
 * ```
 *
 * NOTE: `element` is needed because `QRL`s are relative and need a base location to resolve
 * against. The base location is encoded in the HTML in the form of `<div q:base="/url">`.
 *
 * ## `QRL.resolved`
 *
 * Once `QRL.resolve()` returns, the value is stored under `QRL.resolved`. This allows the value to
 * be used without having to await `QRL.resolve()` again.
 *
 * ## Question: Why not just use `import()`?
 *
 * At first glance, `QRL` serves the same purpose as `import()`. However, there are three subtle
 * differences that need to be taken into account.
 *
 * 1. `QRL`s must be serializable into HTML.
 * 2. `QRL`s must be resolved by framework relative to `q:base`.
 * 3. `QRL`s must be able to capture lexically scoped variables.
 * 4. `QRL`s encapsulate the difference between running with and without Qwik Optimizer.
 * 5. `QRL`s allow expressing lazy-loaded boundaries without thinking about chunk and symbol names.
 *
 * Let's assume that you intend to write code such as this:
 *
 * ```tsx
 * return <button onClick={() => (await import('./chunk-abc.js')).onClick}>
 * ```
 *
 * The above code needs to be serialized into DOM such as:
 *
 * ```
 * <div q:base="/build/">
 *   <button on:click="./chunk-abc.js#onClick">...</button>
 * </div>
 * ```
 *
 * 1. Notice there is no easy way to extract chunk (`./chunk-abc.js`) and symbol (`onClick`) into HTML.
 * 2. Notice that even if you could extract it, the `import('./chunk-abc.js')` would become relative to
 *    where the `import()` file is declared. Because it is our framework doing the load, the
 *    `./chunk-abc.js` would become relative to the framework file. This is not correct, as it
 *    should be relative to the original file generated by the bundler.
 * 3. Next, the framework needs to resolve the `./chunk-abc.js` and needs a base location that is
 *    encoded in the HTML.
 * 4. The QRL needs to be able to capture lexically scoped variables. (`import()` only allows loading
 *    top-level symbols which don't capture variables.)
 * 5. As a developer, you don't want to think about `import` and naming the chunks and symbols. You
 *    just want to say: "this should be lazy."
 *
 * These are the main reasons why Qwik introduces its own concept of `QRL`.

 * This method works like an async memoized function that runs whenever some tracked value changes
 * and returns some data.
 *
 * `useResource` however returns immediate a `ResourceReturn` object that contains the data and a
 * state that indicates if the data is available or not.
 *
 * The status can be one of the following:
 *
 * - 'pending' - the data is not yet available.
 * - 'resolved' - the data is available.
 * - 'rejected' - the data is not available due to an error or timeout.
 *
 * ### Example
 *
 * Example showing how `useResource` to perform a fetch to request the weather, whenever the input
 * city name changes.
 *
 * ```tsx
 * const Cmp = component$(() => {
 *   const cityS = useSignal('');
 *
 *   const weatherResource = useResource$(async ({ track, cleanup }) => {
 *     const cityName = track(cityS);
 *     const abortController = new AbortController();
 *     cleanup(() => abortController.abort('cleanup'));
 *     const res = await fetch(`http://weatherdata.com?city=${cityName}`, {
 *       signal: abortController.signal,
 *     });
 *     const data = await res.json();
 *     return data as { temp: number };
 *   });
 *
 *   return (
 *     <div>
 *       <input name="city" bind:value={cityS} />
 *       <Resource
 *         value={weatherResource}

 * changes to the `state.count` property will cause the `taskFn` to rerun.
 *
 * ```tsx

 *     name: 'Manu',

 *       address: '',
 *       city: '',
 *     },
 *     orgs: [],
 *   });
 *
 *   // useStore() can also accept a function to calculate the initial value
 *   const state = useStore(() => {
 *     return {
 *       value: expensiveInitialValue(),
 *     };
 *   });
 *
 *   return (
 *     <div>
 *       <div>Counter: {counter.value}</div>
 *       <Child userData={userData} state={state} />
 *     </div>
 *   );
 * });
 *
 * function useCounter(step: number) {
 *   // Multiple stores can be created in custom hooks for convenience and composability
 *   const counterStore = useStore({
 *     value: 0,
 *   });
 *   useVisibleTask$(() => {
 *     // Only runs in the client
 *     const timer = setInterval(() => {
 *       counterStore.value += step;
 *     }, 500);
 *     return () => {
 *       clearInterval(timer);
 *     };
 *   });
 *   return counterStore;
