React Production Performance Monitoring — Having users complaining about your app being slow ‘is not a great policy’, says Kent, so it’s worth measuring the performance of your components in production yourself.. and luckily React provides a great way to do so.

Fix The Slow Render Before You Fix The Re-Render — Kent covers how to start optimizing your React app renders before focusing on reducing the number of re-renders. Essentially, fix the underlying performance ‘disease’ rather than reducing the symptoms.

One Simple Trick to Optimize React Re-renders — An illustration of a natural, built-in performance optimization that doesn’t require using things like React.memo, PureComponent, or shouldComponentUpdate.

When to useMemo and useCallback — An interesting demonstration of how abstractions and performance optimizations can sometimes come with a cost that outweighs the benefit, focusing here on the useMemo and useCallback hooks.
