How to optimize a React JS app bundle performance to load under 3s | Code splitting | Lazy loading

Tutorial on how to optimize React JS application performance to load in less than 3 seconds on a mobile connection using the simple Sliced Bread technique with React.lazy() and Suspense. This easy to learn approach often reduces bundle sizes, too. As a result, your application will consume less CPU and memory and will load faster than your competition. Full code samples below!

Modus has used this React performance optimization technique over and over again with Global Fortune 500 companies with incredible success. Our clients report better customer satisfaction and much better conversion rates (this means profit!) after adopting our approach to improve the speed of their web experience.
