During a React.js live coding interview for a mid to senior level position in 2024, you can expect to be asked to demonstrate your ability to build complex, interactive web applications using React.js. You will likely be given a coding challenge or project to complete within a set time frame, during which you will be expected to showcase your knowledge of React.js best practices, performance optimization techniques, and proficiency with popular libraries and tools.
Here are some key tips and strategies to help you prepare for and succeed in a React.js live coding interview at the mid to senior level in 2024:
1. Familiarize yourself with the latest React.js features and updates: stay up to date with the latest developments in React.js, including new features, performance improvements, and best practices. Make sure you are comfortable using hooks, context API, lazy loading, and other advanced React.js concepts.
2. Practice solving coding challenges and building projects: spend time practicing coding challenges and building projects using React.js. This will help you sharpen your problem-solving skills, understand common patterns and techniques, and become more comfortable working with the framework.
3. Review your understanding of state management: understand how to manage state in React.js applications, including using local state, props, and context API. Familiarize yourself with popular state management libraries like Redux or MobX, and be prepared to discuss their pros and cons.
4. Optimize performance and handle side effects: learn how to optimize the performance of React.js applications by using techniques such as memoization, code splitting, and lazy loading. Understand how to handle side effects, such as data fetching or interacting with APIs, using hooks like useEffect and useMemo.
5. Practice working with third-party libraries and tools: be familiar with popular libraries and tools commonly used with React.js, such as React Router, Redux Toolkit, Material-UI, and React Testing Library. Be prepared to demonstrate your ability to integrate and use these tools effectively in your projects.
6. Communicate clearly and confidently: during the live coding interview, make sure to communicate your thought process, explain your code decisions, and ask for clarification if needed. Demonstrate your problem-solving skills, ability to work under pressure, and willingness to learn and adapt.
7. Show your creativity and problem-solving skills: use the coding challenge or project as an opportunity to showcase your creativity, innovation, and ability to think outside the box. Be open to feedback and suggestions, and be willing to explore different solutions to a given problem.
By following these tips and strategies, you can feel more prepared and confident when facing a React.js live coding interview for a mid to senior level position in 2024. Remember to practice regularly, stay up to date with the latest React.js developments, and approach the interview with a positive attitude and a willingness to learn and grow. Good luck!

You could avoid the dependency on the “colorList” state inside of “handleClick” by using the callback from the “setColorList” function. So “setColorList((prevState) => { …. })” and add the logic for modifying the state inside that callback and return new state. This way, when you wrap your “handleClick” function with “useCallback”, the dependency array can be empty, hence the function will stay the same and Squares that didn’t change will not rerender.
Btw I really like your videos. Keep up the good work!
This was very messy, usually I really like your videos but this one was quite unstructured and jumping around the code making it difficult to follow as a viewer. At any rate, I really like your channel. Keep it up.

"Click green"? What? In the list? What List? A list I create, even though it's the starting point?
I wouldn't start until I got to clarify the requirements, and if they took offence to me basically calling their question shit, I'd leave.
Interviews aren't 1 way, and this smacks of useless.
