For fine-grained control over re-renders, `useReducer()` can be combined with `React.memo` and `useCallback` to optimize performance by preventing unnecessary renders. Integration with External Libraries: Integrating React with external libraries like D3.js or Three.js often requires a centralize...
The treemap shows that there are many unused codes, but js is a packaged chunk. I don't know the specific situation. Is there any way to optimize it? Most frequent: When there are many react components, drag and drop encounters performance problems, causing the page to freeze ...
React’s new concurrent mode allows your interface to be rendered while data fetching is in progress, providing an improved render lifecycle and a simple way to achieve parallel data fetching for multiple components.
When reusing the content of the React Native container, the global variables of the previous session will be maintained, which may easily cause business logic errors. When the same engine loads different bundles, it may be unknown whether the JavaScript context and the newly loaded code can achie...
We introduced React.memo to optimize re-renders. While the title component doesn't re-render (as expected), the "count" components for age and salary still do. The culprit? The incrementSalary function. Even though it has the same functionality, a new function is created every time the par...
React.memo is a function that you can use to optimize the render performance of purefunction componentsand hooks. It has been introduced in React v16.6.. Memoderives frommemoization. It means that the result of the function wrapped in React.memo is saved in memory andreturns the cached result...
