React Performance Tuning: Mastering useMemo for Better User Experience

Comments 1 Comment

In React, useMemo is a powerful hook that helps optimize performance by memoizing, or caching, the results of expensive calculations. This prevents unnecessary re-renders, ultimately leading to a smoother user experience. What is memoization? Think of it like remembering a phone number once you’ve looked it up. Memoization stores the result of a function call based on its input values. If the same input is used again, the cached result is returned instead of re-executing the function. When to use…
