To implement custom hooks for managing video player state, you'll create a reusable hook that handles video player functionality. This hook will manage the video's current time, playback state, volume, and mute state. Here's how to implement it: ```javascript import { useState, useEffect } from 'react'; export const useVideoPlayer = () => { const [isPlaying, setIsPlaying] = useState(false); const [currentTime, setCurrentTime] = useState(0); const [volume, setVolume] = useState(1); const [isMuted, setIsMuted] = useState(false); const [duration, setDuration] = useState(0); // Event handlers const handlePlayPause = () => { setIsPlaying(!isPlaying); }; const handleVolumeChange = (e) => { const newVolume = parseFloat(e.target.value); setVolume(newVolume); setIsMuted(newVolume === 0); }; const handleMuteToggle = () => { setIsMuted(!isMuted); setVolume(isMuted ? 1 : 0); }; // Update current time when playing useEffect(() => { let interval; if (isPlaying) { interval = setInterval(() => { setCurrentTime((prev) => (prev >= duration ? 0 : prev + 1)); }, 1000); } return () => clearInterval(interval); }, [isPlaying, duration]); return { isPlaying, currentTime, volume, isMuted, handlePlayPause, handleVolumeChange, handleMuteToggle, }; }; ``` This custom hook provides: - State management for playback controls - Volume control with mute functionality - Time tracking for the video - Event handlers for player controls To use this hook in your VideoPlayer component: ```javascript import React from 'react'; import { useVideoPlayer } from './useVideoPlayer'; const VideoPlayer = ({ videoSrc }) => { const { isPlaying, currentTime, volume, isMuted, handlePlayPause, handleVolumeChange, handleMuteToggle, } = useVideoPlayer(); return (

); }; ``` This implementation provides a clean separation of concerns and makes the video player state management reusable across components. **Next Steps:** 1. Connect this hook with your video gallery component 2. Implement the same state management pattern for other components that need state 3. Add error handling for video loading failures **Further Reading:** - [React Custom Hooks Documentation](https://react.dev/custom-hooks) - [React State Management Best Practices](https://react.dev/learn/state) - [Managing State with React Hooks](https://react.dev/learn/state)
