Preparing for ReactJS Coding Interviews? Start with these questions: => Build a counter app with increment/decrement => Create a form with validation => Fetch data from an API and display it => Build a search input with debounce => Implement a todo list (add, delete, mark complete) => Create a reusable modal component => Build a dropdown with multiselect. => Implement pagination for a list => Create a custom hook (e.g., useFetch) => Optimize a slow rendering component => Implement infinite scrolling => Manage global state in an app => Handle API errors globally => Build a dynamic form (fields based on config) Follow up questions interviewers might ask: => How will you prevent unnecessary re-renders? => How will you manage form state and errors? => How will you handle loading, error, and empty states? => How will you optimize API calls? => How will you structure state for scalability? => How will you manage open/close state cleanly? => How will you handle controlled vs. uncontrolled behavior? => How will you handle large datasets efficiently? => How will you make custom hooks reusable and robust? => When will you use React.memo, useMemo, and useCallback? => How will you detect scroll position and load more data? => Context API vs Redux: What would you choose and why? => How will you design error boundaries or fallback UI? => How will you make dynamic forms scalable and maintainable? #ReactJS #FrontendDevelopment #CodingInterview #JavaScript #WebDevelopment #Developers
Solid list! I'd add: "Build a simple authentication flow" — that's where many juniors struggle. Also, practicing with useMemo/useCallback before interviews saves a lot of pain. #reactjs #interviewtips #webdevelopment
