Do you ever feel like you don't have full control over your React app? Does it seem like your UI is being controlled by an other-worldly force?

Learn about more niche tools that React provides, such as memo, useTransition, and Suspense, and how they can be used to optimize your app. We'll dive into practical scenarios and see how these tools can help us write better mapping applications using the ArcGIS Maps SDK for JavaScript.
