Explain the concept of error boundaries in React-Redux.

Error boundaries in React-Redux are components that catch errors within their child component tree, preventing the entire app from crashing. They display a fallback UI when an error occurs, improving user experience by gracefully handling errors. Error boundaries can be implemented around connected components, helping isolate and manage errors within specific parts of the application.

Error boundaries in React-Redux are:

• Error Handling Component: An error boundary is a React component that catches errors occurring in its child components during rendering, lifecycle methods, and constructors.
• Prevents App Crashes: Error boundaries prevent the entire React application from crashing due to errors in a specific component or subtree. Instead, they display a fallback UI, allowing the rest of the application to remain functional.
• Boundary Definition: Error boundaries are defined using special lifecycle methods like componentDidCatch, which intercepts errors thrown by components in its subtree.
• Fallback UI: When an error occurs within an error boundary’s child components, the boundary renders a fallback UI specified by the developer. This UI can be a simple error message or a more complex component.
• Nested Boundaries: Error boundaries can be nested within each other, providing granular control over error handling at different levels of the component hierarchy.

Error boundaries in React-Redux help prevent application crashes by catching errors and displaying fallback UIs, ensuring a smoother user experience.
