Optimizing Performance with useState() in React ApplicationsApr 27, 2025 am 12:22 AMuseState()iscrucialforoptimizingReactappperformanceduetoitsimpactonre-rendersandupdates.Tooptimize:1)UseuseCallbacktomemoizefunctionsandpreventunnecessaryre-renders.2)EmployuseMemoforcachingexpensivecomputations.3)Breakstateintosmallervariablesformor
Sharing State Between Components Using Context and useState()Apr 27, 2025 am 12:19 AMUse Context and useState to share states because they simplify state management in large React applications. 1) Reduce propdrilling, 2) The code is clearer, 3) It is easier to manage global state. However, pay attention to performance overhead and debugging complexity. The rational use of Context and optimization technology can improve the efficiency and maintainability of the application.
The Impact of Incorrect Keys on React's Virtual DOM UpdatesApr 27, 2025 am 12:19 AMUsing incorrect keys can cause performance issues and unexpected behavior in React applications. 1) The key is a unique identifier of the list item, helping React update the virtual DOM efficiently. 2) Using the same or non-unique key will cause list items to be reordered and component states to be lost. 3) Using stable and unique identifiers as keys can optimize performance and avoid full re-rendering. 4) Use tools such as ESLint to verify the correctness of the key. Proper use of keys ensures efficient and reliable React applications.

Common Mistakes to Avoid When Working with useState() in ReactApr 27, 2025 am 12:08 AMuseState is often misused in React. 1. Misunderstand the working mechanism of useState: the status will not be updated immediately after setState. 2. Error update status: SetState in function form should be used. 3. Overuse useState: Use props if necessary. 4. Ignore the dependency array of useEffect: the dependency array needs to be updated when the state changes. 5. Performance considerations: Batch updates to states and simplified state structures can improve performance. Correct understanding and use of useState can improve code efficiency and maintainability.

React's Performance Bottlenecks: Identifying and Optimizing Slow ComponentsApr 26, 2025 am 12:25 AMReact performance bottlenecks are mainly caused by inefficient rendering, unnecessary re-rendering and calculation of component internal heavy weight. 1) Use ReactDevTools to locate slow components and apply React.memo optimization. 2) Optimize useEffect to ensure that it only runs when necessary. 3) Use useMemo and useCallback for memory processing. 4) Split the large component into small components. 5) For big data lists, use virtual scrolling technology to optimize rendering. Through these methods, the performance of React applications can be significantly improved.
Alternatives to React: Exploring Other JavaScript UI Libraries and FrameworksApr 26, 2025 am 12:24 AMSomeone might look for alternatives to React because of performance issues, learning curves, or exploring different UI development methods. 1) Vue.js is praised for its ease of integration and mild learning curve, suitable for small and large applications. 2) Angular is developed by Google and is suitable for large applications, with a powerful type system and dependency injection. 3) Svelte provides excellent performance and simplicity by compiling it into efficient JavaScript at build time, but its ecosystem is still growing. When choosing alternatives, they should be determined based on project needs, team experience and project size.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
