Welcome to your interview.
The question is on your right: Avoiding React Re-render Pitfalls. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
What are the common pitfalls when working with React state, and how do you prevent unnecessary re-renders?
