React cache

1. react-cache:
- react-cache is a basic cache for React applications. It is meant to be used alongside experimental React features and is not recommended for use in production applications due to its unstable API[1].

2. Windows Cache:
- The Windows cache can be used to store single cache data in React JS. This involves defining a function to access named data in the cache storage and putting custom data into the browser cache. The cache is accessed using the `caches.open(cacheName)` method[2].

3. React Cache Function:
- The React Cache Function is a built-in feature of React Server Components. It allows caching the result of a data fetch or computation. This API is only usable in React Server Components and is not a replacement for other caching libraries like React Query[3].

4. useMemo and useCallback Hooks:
- These hooks are used to memoize values and functions, respectively. They help in reducing unnecessary re-renders by caching the results of expensive computations. `useMemo` memoizes the result of a function call, while `useCallback` memoizes the actual reference of a function[4][5].

5. Example Usage:
- Here is an example of using the `cache` function to avoid recomputing results when passing the same arguments to a function. This example shows how the `cache` function can be used to memoize a function and avoid unnecessary computations[5].

Example Code

jsx
import { cache, useState, useReducer } from "react";

const alertCounter = cache((id) => {
  alert(id);
});

function App() {
  const [counter, setCounter] = useState(0);
  const [_, rerender] = useReducer(() => ({ }), {});

  alertCounter(counter);

  return (
    <div>
      <button onClick={() => setCounter((v) => v + 1)}>Add to {counter}</button>
      <button onClick={rerender}>Rerender</button>
      <input key={Math.floor(Math.random() * 10)} />
    </div>
  );
}
