Node.js streams enable efficient data processing by handling information piece by piece. They excel in file processing, data transformation, network communication, and real-time data handling, improving performance and memory usage.

Testing custom React hooks: Use renderHook, mock dependencies, control time with Jest timers, simulate context, handle Redux, and test complex scenarios. Ensure reliability through comprehensive testing.

Mastering Modern JavaScript Applications with Rollup.js

CI/CD for Node.js using Jenkins and GitHub Actions automates building, testing, and deploying. Integrate tools, use environment variables, fail fast, cache dependencies, monitor, and consider Docker for consistent builds.

Jest with CI/CD pipelines automates testing, enhances code quality, and accelerates development. It catches bugs early, ensures consistency, and boosts confidence in shipping code faster and more reliably.

Node.js optimization: Memory management, CPU efficiency, I/O operations, error handling, logging, database queries, dependency management, and caching. Key focus on async operations, worker threads, and avoiding event loop blocking for better performance.

Unlocking the Creative and Interactive Potential of DOM Manipulation

GraphQL and Jest combine for robust API testing. Jest's simple syntax enables easy query and mutation checks. Mock resolvers, snapshot testing, and error handling ensure comprehensive coverage. Client-side testing with Apollo enhances full-stack confidence.

React PWAs combine web and native app features. They load fast, work offline, and can be installed. Service workers enable caching and push notifications. Manifest files define app behavior. Code splitting improves performance.

React's concurrent rendering and Suspense optimize performance. Prioritize updates, manage loading states, and leverage code splitting. Avoid unnecessary re-renders, manage side effects, and use memoization. Focus on user experience and perceived performance.
