Optimizing Functional Components with React.memo React.memo is a powerful performance optimization tool that prevents unnecessary re-renders of functional components. Here’s how to use it effectively to boost your application’s performance…..
In React, rendering large lists without using virtualization can lead to significant performance issues, especially when dealing with hundreds or thousands of items. Virtualization is a technique that ensures only….
In React, passing new object references in props on every render can lead to unnecessary re-renders of child components, even if the actual data inside the objects hasn’t changed. This….
In React, expensive computations (such as complex calculations or large data processing) can slow down the app, especially when they are recalculated on every render. To optimize performance, React provides….
Optimizing Performance by Avoiding Unnecessary Renders from Inline Functions Inline functions in React components can lead to performance issues by causing unnecessary re-renders of child components. Here’s a deep dive….
Unnecessary re-renders in React occur when the component tree re-renders more often than needed, affecting performance. This can lead to slower UI updates, especially in large applications, as React may….
In React, the useEffect hook allows you to perform side effects (e.g., data fetching, subscriptions, timers) in function components. One common problem developers face when using useEffect is infinite re-renders,….
When working with APIs in React, it’s important to ensure that data is available before trying to access it. Attempting to use API data before it has been successfully fetched….
In React, you should avoid making API calls directly inside the render() method (or inside a component’s return statement). Calling an API in render() will result in unnecessary and repeated….
In React, when you make asynchronous operations like API requests inside a component (using fetch, axios, or other libraries), it’s important to clean up those operations when the component unmounts…..
