import React, { useState } from 'react'; import { View, Text } from 'react-native'; const Counter = () => { const [count, setCount] = useState(0); return ( <View> <Text>Count: {count}</Text> <Button title="Increment" onPress={() => setCount(count + 1)} /> </View> ); }; The useEffect hook is used to handle side effects in functional components. It takes a function as an argument that is executed after the component has rendered.

import React, { useReducer } from 'react'; import { View, Text } from 'react-native'; const initialState = { count: 0 }; const reducer = (state, action) => { switch (action.type) { case 'INCREMENT': return { count: state.count + 1 }; case 'DECREMENT': return { count: state.count - 1 }; default: return state; } }; const Counter = () => { const [state, dispatch] = useReducer(reducer, initialState); return ( <View> <Text>Count: {state.count}</Text> <Button title="Increment" onPress={() => dispatch({ type: 'INCREMENT' })} /> <Button title="Decrement" onPress={() => dispatch({ type: 'DECREMENT' })} /> </View> ); }; In addition to the built-in hooks, you can also create custom hooks to extract reusable logic from your components.

It takes a reducer function and an initial state as arguments and returns an array with two elements: the current state and a dispatch function. import React, { useState } from 'react'; import

import React, { useState, useEffect } from 'react'; import { View, Text } from 'react-native'; const FetchData = () => { const [data, setData] = useState([]); useEffect(() => { fetch('https://api.example.com/data') .then(response => response.json()) .then(data => setData(data)); }, []); return ( <View> <Text>Data: {data.map(item => item.name).join(', ')}</Text> </View> ); }; The useContext hook is used to access context in functional components. It takes a context object as an argument and returns the current value of the context. Custom hooks are functions that use one or
