Understanding the Need for Optimization
When rendering a list of items in React, each item typically corresponds to a component. If the list is extensive and components are re-rendered unnecessarily, it can impact performance and user experience. The useMemo
hook helps mitigate this issue by memoizing values based on dependencies, preventing unnecessary re-renders.
Optimizing Performance of List Rendering with useMemo Hook in React
List rendering is a common task in web development, especially in React applications where components often display dynamic lists of data. However, rendering large lists can lead to performance issues if not handled efficiently. In this article, we’ll explore how to optimize the performance of list rendering in React using the useMemo
hook.
