"Effective Use of UseEffect" by Ben Okkema
React beginners know to use the useEffect hook to respond to changes in information on the page. However, the hook has a not-so-often used return value for gracefully removing a component from scope. We'll explore using this clean up function to abort network calls and share lessons learned on its implementation in an alert provider.
Ben Okkema is a Technical Lead at nvisia. Over the last two years has performed a variety of roles one of which was to modernize legacy applications by rewriting them in React. When not at the keyboard, you can usually find him on his bike or in his garden.

"Improving React Performance using UseMemo and UseCallback" by Bruce Smith
One often missed area in React is performance. Sometimes we have to massage data, process inputs or make calculations on the fly; these are all normal things to do in a React application, but if done carelessly they can cause a performance nightmare. We'll go through a scenario where we look into the UseMemo hook to help us avoid expensive operations from running unnecessarily, and then we'll implement UseCallback to avoid re-rendering child components.
