Interview Challenge: Could You Write useEffect From Scratch?

React's useEffect hook is a crucial part of the framework, but implementing it from scratch can be challenging. A coding interview task asks candidates to recreate useEffect within an hour, focusing on dependency handling and common use cases. The challenge emphasizes TypeScript implementation and encourages candidates to think through the problem before coding. This exercise tests a developer's deep understanding of React's core functionality and their ability to recreate complex features under time pressure.
