Avoiding Infinite Loops in React’s useEffect One of the most common React pitfalls is creating infinite loops with useEffect due to incorrect dependency management. These loops can crash your application….
The Importance of useCallback for Event Handlers in Child Components When passing event handlers to child components in React, failing to use useCallback can lead to performance issues. Here’s what….
Arrow Functions in JSX Without Memoization A common React performance pitfall is using inline arrow functions in JSX without proper memoization, which can cause unnecessary re-renders of child components. The….
Optimizing useEffect Dependencies A common React performance pitfall is including unnecessary dependencies in the useEffect dependency array, which can lead to excessive re-renders, infinite loops, or stale closures. The Problem:….
Optimizing Performance with useMemo A common React performance pitfall is not memoizing expensive computations, which can lead to unnecessary re-calculations and sluggish user interfaces, especially in complex components. The Problem:….
Handling Non-Serializable Values in useEffect Dependencies A common React performance pitfall occurs when passing non-serializable values (like functions, class instances, or complex objects) into a useEffect dependency array. This can….
The Importance of useCallback for Event Handlers in React When passing event handlers to child components, not using useCallback can lead to performance issues. Here’s why it matters and how….
Arrow Functions in JSX and Re-render Performance Issues Using arrow functions directly in JSX can cause unnecessary component re-renders, which is a common performance pitfall in React applications. The Problem:….
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….
