React Error Boundaries Explained | Prevent App Crashes & Handle Errors Safely

Error Boundaries in React are a critical feature used to catch JavaScript runtime errors and prevent entire applications from crashing. In this YouTube Short, you’ll learn what Error Boundaries are, why they are important, and how they work in real React applications.

This video explains how Error Boundaries catch errors during rendering, lifecycle methods, and constructors, and how they display a fallback UI instead of breaking the whole app. You’ll also understand what Error Boundaries do not catch, why they are built using class components, and where they should be used in production projects.

Perfect for React beginners, frontend developers, and React interview preparation, this short simplifies error handling in React with clear explanations.

Topics covered:
✔ What are Error Boundaries in React
✔ Why React apps crash without them
✔ Fallback UI concept
✔ Error handling best practices
✔ Interview-ready explanation
