A React hook that provides callback memoization with deep dependency comparison, offering an alternative to `useCallback` with more sophisticated change detection. ## Key Components - **`useMemoizedCallback`** - Main hook function that accepts a callback and dependencies array - **`callbackRef`** - Ref to store the current callback function - **`dependenciesRef`** - Ref to store the previous dependencies for comparison - **Deep comparison logic** - Uses `Object.is()` to detect changes in dependency values ## Usage Example ```typescript import { useMemoizedCallback } from './use-memoized-callback' function MyComponent({ userId, filters }: Props) { // Memoizes callback with deep dependency comparison const handleSearch = useMemoizedCallback( (query: string) => { return searchAPI(query, userId, filters) }, [userId, filters] // Dependencies are deeply compared ) // Callback only recreates when userId or filters actually change return ( ) } // Complex object dependencies const complexCallback = useMemoizedCallback( (data: any) => processData(data, config), [config.nested.value, config.enabled] // Fine-grained dependency tracking ) ``` The hook updates the callback reference on every render but only triggers memoization updates when dependencies actually change, providing more precise control over callback recreation than standard `useCallback`.
