Star Rating React JS Interview Challenge | Live Coding React Interview Questions #7

Learn how to solve and answer the React JS Star Rating Interview Question.
We start by reviewing the simple UI design and expected behavior, then move step-by-step into the implementation using React functional components and the useState hook. You’ll learn how to dynamically generate stars, handle click events, update the rating state, and apply conditional styling to reflect the selected rating.

This type of task is very common in front-end technical interviews, and it’s a great exercise for practicing core React concepts such as:
- Component structure
- State management
- Array mapping for rendering UI
- Event handling
- Conditional rendering and styling

By the end of the video, you’ll have a clean and reusable Star Rating component that can be easily extended (for example, changing the number of stars or styling).

What you’ll learn in this video:
- How to create a Star Rating component in React
- How to generate elements dynamically using arrays
- How to use the useState hook for interactive UI
- How to handle click events in React
- How to implement conditional styling for rating logic
