Error boundaries in React are a crucial aspect of error handling in React applications. They are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of the component tree that crashed. They’re like a JavaScript catch{}block but for components. Before the introduct...
