Article Introduction：The answer is: you should first master native JavaScript and then learn the framework. Because frameworks are just tools, JS is the foundation, not understanding JS will make it difficult to troubleshoot bugs and deal with interview questions; understanding native JS can help you better understand the design ideas of the framework; learning to be able to operate DOM, handle events, use Promise, understand this and prototype chains, and write simple interaction functions can start learning the framework; it is recommended to start with HTML CSS native JS first, learn while doing, read more documents, read less quick courses, and write projects by hand.

Article Introduction：ShadowDOM is a browser-native component encapsulation mechanism used to isolate structures and styles; VirtualDOM is a programming technique that optimizes UI updates. 1. ShadowDOM belongs to WebComponents, creates independent and isolated DOM trees to prevent style pollution, and is suitable for building reusable components such as or. 2. VirtualDOM is implemented by frameworks such as React, which simulates real DOM in memory, minimizes update operations through the Diff algorithm, and improves performance. 3. The core difference between the two is their different functions: ShadowDOM focuses on packaging, while VirtualDOM focuses on efficient updates; different implementation methods: the former is native browser support, while the latter is JS simulation; application field

Article Introduction：Webpack is suitable for large applications, with comprehensive functions but complex configuration; Rollup focuses on packaging libraries, with small output size and strong Tree-shaking; Vite is based on native ES modules, with fast development speed and suitable for modern frameworks. 1. Webpack is centered on "Everything is a module" and supports code segmentation and rich plug-ins. It is suitable for complex projects but slow to build; 2. Rollup supports ESM by default, outputs clean code, suitable for NPM library release, but weakly handles non-JS resources; 3. Vite uses browser native ESM, does not package in the development stage, starts quickly and supports mainstream frameworks, suitable for new projects, but TS and migration support needs to be improved.

Article Introduction：WebAssembly (Wasm) is a binary instruction format suitable for image and video processing due to its near-native execution speed. 1. It supports compiling into intermediate formats in multiple languages, and runs efficiently in the browser; 2. Image and video processing involves a large amount of calculations, and Wasm is more efficient than JavaScript; 3. Select language and tool chain when using it, encapsulate functions to receive image data, and JS passes data to Wasm for processing and then passes the results back; 4. Video processing requires controlling frame rate, synchronization and memory management, JS grabs frames and passes them to Wasm for processing and then synthesis; 5. Pay attention to data format conversion, memory allocation and release, performance bottleneck positioning, and browser compatibility issues.

Article Introduction：A practical guide to improving the performance of React Native applications Key Points Balancing the animation processing of JavaScript (JS) threads and main threads to improve application performance. Use the useNativeDriver attribute and InteractionManager to manage this balance. Avoid unnecessary component re-rendering. Tips include: memorizing components and functions, using useCallback wisely, avoiding updating local states with Redux states, and avoiding inline functions. Optimize images to increase application speed. Use SVG icons and images, WebP image format (lossless image quality), and cache images to speed up rendering. Using stable npm packages and Fla

Article Introduction：Nanny State: A streamlined Vanilla JS state management library Nanny State is a mini library designed to simplify the process of building state-based web applications using native JavaScript. It's similar to React, but with less overhead, no need to learn new syntax. It uses a single application-wide state object instead of letting each component have its own state. It was inspired by HyperApp and has many similarities with Elm. This article will explain how Nanny State works and demonstrate its functionality with several examples. Key points: Nanny State Introduction: Nanny S

Article Introduction：Use Electron and JavaScript to build cross-platform desktop applications based on HTML, CSS, and JS; 2. You need to distinguish between the main process (manage windows and life cycles) and the rendering process (processing UI and communicating through IPC); 3. Use electron-builder to package and generate installation files for each platform; 4. Optimize performance, ensure secure configuration, and use native modules to improve the experience - mastering Web skills can develop complete desktop applications, which are still suitable for most cross-platform scenarios despite the size and memory overhead.

Article Introduction：WebAssembly (WASM) is a binary format that runs in a browser, suitable for CPU-intensive tasks. The reasons include: 1. Fast execution speed and close to native code; 2. Supports multiple system-level languages such as Rust and C; 3. Runs in a secure sandbox; 4. Cross-platform compatibility. The key steps to integrate WASM into front-end projects are: 1. Select toolchains such as Rust and wasm-pack; 2. Write and export Rust functions; 3. Compile into .wasm files; 4. Load and call them on the front-end. Applicable scenarios include pure computing tasks such as image processing, encryption, data compression, etc., and the performance can be 5 to 10 times higher than JS. However, tasks such as DOM operations that rely on browser APIs should still use JS

Article Introduction：The new HTML5 input type improves the form experience, the main methods include: 1. Use email and url types to realize automatic format verification and optimize the mobile keyboard; 2. Use number and range to process numerical input, which are suitable for accurate values ??and sliding selection respectively; 3. Use date series types to call the native date selector to improve time input efficiency. These features reduce the burden of front-end verification, but basic verification still needs to be supplemented by the server. Some types need to be combined with JS libraries to ensure compatibility on old devices.

Article Introduction：The key to making interactive HTML prototypes is to master the coordination of structure, style and behavior. 1. Use basic HTML to build structures, such as buttons and pop-up elements; 2. Use CSS to control state changes, replace frequent DOM operations through class switching, improve debugging efficiency; 3. Use native JS to achieve simple interaction, such as clicking to show or hide elements, keep the code lightweight; 4. Add animation effects to improve the experience, such as pop-ups fade in and out, but avoid excessive complexity. Through these steps, you can quickly verify ideas and demonstrate a clear process.

Article Introduction：Why choose H5 micro front-end? Because it can split large applications into small independent modules, improve development efficiency and reduce maintenance costs, it is suitable for projects with frequent team collaboration and fast changes in demand. Advantages include flexibility in the technology stack (supports React, Vue, native JS), support for rapid iteration (local updates do not affect the overall situation), and team decoupling (clearer internal work between the front and back ends and the front end). 1. The main sub-application loading mechanism is recommended to use a JS runtime loading scheme similar to qiankun, which supports life cycle management; 2. The route management is recommended to use sub-application self-management routing to maintain integrity and facilitate migration; 3. The communication mechanism can be encapsulated through a unified interface, using event bus or shared state objects, avoiding direct operation of windows. Other things to note
