React Performance Optimization: Lazy Loading

React.lazy has built-in error handling
Dynamic import() works with server-side rendering but React.lazy doesn't
React.lazy integrates with React's component model while dynamic import() just returns a Promise
The main difference between React.lazy and manually using dynamic import() is that React.lazy integrates with React's component model while dynamic import() just returns a Promise. React.lazy converts the Promise returned by dynamic import() into a React component that can be directly used in JSX. It also integrates with Suspense for loading states. With manual dynamic import(), you would need to handle the Promise resolution yourself, manage component state for loading/error conditions, and implement your own rendering logic, which is more complex and error-prone.
Dynamic import() is deprecated in favor of React.lazy
