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
