📊 Transcript
Common performance issues in React related to slow rendering caused by inefficient component updates.
00:50
React's lifecycle is explained, including mounting, unmounting, and re-rendering processes.
Inefficient state updates trigger unnecessary component re-renders, leading to slow rendering.
Potential performance risks associated with custom hooks are highlighted, with solutions provided to optimize rendering speed.
Understanding React's lifecycle and optimizing state management can improve app performance and user experience.
State management in React focuses on the impact of props and state updates on re-renders.
05:58
Props do not cause re-renders, but state updates do trigger them.
Moving state down the render tree by isolating state-related components optimizes performance and avoids unnecessary re-renders.
This approach simplifies the re-render process and sets the stage for further discussions on React rendering mechanisms and performance optimization strategies.
