A React hook that delays the updating of a value until a specified time period has passed without changes, useful for optimizing performance in search inputs and API calls. ## Key Components - **`useDebounce`** - Generic hook that accepts any value type and returns a debounced version - **Parameters**: - `value: T` - The value to debounce - `delay: number` - Delay in milliseconds (defaults to 500ms) - **Returns**: `T` - The debounced value that updates only after the delay period ## Usage Example ```typescript import { useDebounce } from './use-debounce' import { useState, useEffect } from 'react' function SearchComponent() { const [searchTerm, setSearchTerm] = useState('') const debouncedSearchTerm = useDebounce(searchTerm, 300) // API call only triggers when user stops typing for 300ms useEffect(() => { if (debouncedSearchTerm) { // Perform search API call console.log('Searching for:', debouncedSearchTerm) } }, [debouncedSearchTerm]) return ( setSearchTerm(e.target.value)} placeholder="Search..." /> ) } ``` The hook prevents excessive API calls or expensive operations by only updating the debounced value when the input value remains unchanged for the specified delay period.
