React Interview Coding Challenges - Implement An Expandable Tree Component

In this video, we tackle a popular React coding challenge often seen in frontend interviews: implementing a dynamic and reusable tree component. This challenge is perfect for practicing recursion, state management, and designing scalable React components.

We’ll start with a simple one-level static tree, then enhance it using recursion to handle nested data structures. Finally, we’ll make the tree expandable and share tips on how to approach and explain your solution during a coding interview.
