useContext hook has made React Context API so pleasant to work with that many people are even suggesting that we drop external state management solutions and rely on the built-in alternative instead.

Performance optimizations ALWAYS come with a cost but do NOT always come with a benefit. Let's talk about the costs and benefits of useMemo and useCallback.

Learn how to use React.memo, some common pitfalls you might encounter, and why you shouldn't use React.memo for all your components.

We study React applications performance from the ground up, the processes involved, the tools to measure and identify slow parts, the important metrics to take in account, how these impact the UX and the various ways there are available to make applications super fast and smooth.
