The new React “use()” hook in 15mins
In this video, I'll teach you how to use the brand new use() hook in React. The use() hook can be used to read data from promises and context. Additionally, while the promise is being resolved by the use() hook, you can show loaders using the Suspense component and error messages using the ErrorBoundary component. The hook can also be called inside if-else statements and loops, making it extra special.
