Mobile App Development with React Native

Mobile app development in React Native allows you to build cross-platform mobile applications using React. Install it with: npm install -g react-native Create a new React Native project: npx react-native init MyMobileApp cd MyMobileApp npx react-native run-android Explore React Native components and navigation for mobile app development. Optimizing Performance React applications can benefit from performance optimizations. Utilize techniques like memoization, code splitting, and lazy loading to enhance the user experience. // MemoizedComponent.js import React, { useMemo } from 'react'; const MemoizedComponent = ({ data }) => { const processedData = useMemo(() => { // Expensive data processing logic return processData(data); }, [data]); return <div>{processedData}</div>; }; Continuous Integration and Deployment (CI/CD) Set up CI/CD pipelines to automate testing and deployment processes. Platforms like GitHub Actions, GitLab CI, or Travis CI ca
