This article is about the Errors Handling in React Components using TypeScript
Not handled error in any part of the UI could crash the whole application.
Error Boundaries only catch errors in the components below them in the tree.
As of React 16, errors that were not caught by any error boundary will result in unmounting of the whole React component tree.
Catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI.
Use JS error reporting services, so that you can learn about unhandled exceptions as they happen in production, and fix them.
