The operating environment of this tutorial: Windows 7 system, HTML5 version, Dell G3 computer. The comment tag of
html is "<!--...-->", which is used to insert comments in the source document.
In the HTML code, the text between the <!-- and --> tags is the comment of the document, and the content of the comment does not will be displayed on the browser page. Comments are only visible when you open the document in a text editor, or with your browser's "View Source" option.
In a large document, comments can be used to indicate the beginning and end of the block, which can facilitate search, and comments can also be used to prevent certain content from being displayed.
When writing a lot of code, it is a good habit to comment the key code. Commenting to explain the intention of a certain piece of code can help remind yourself or others who need to work on this website. Understand what this code does.
It is also a good habit to use comments to hide scripts, so that browsers that do not support scripts will not display the script as plain text. Such as:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body> <!--这是一个注释，注释在浏览器中不会显示--> <p>这是一个段落</p> </body> </html>

Frontend Development with React: Advantages and TechniquesApr 17, 2025 am 12:25 AMThe advantages of React are its flexibility and efficiency, which are reflected in: 1) Component-based design improves code reusability; 2) Virtual DOM technology optimizes performance, especially when handling large amounts of data updates; 3) The rich ecosystem provides a large number of third-party libraries and tools. By understanding how React works and uses examples, you can master its core concepts and best practices to build an efficient, maintainable user interface.
React vs. Other Frameworks: Comparing and Contrasting OptionsApr 17, 2025 am 12:23 AMReact is a JavaScript library for building user interfaces, suitable for large and complex applications. 1. The core of React is componentization and virtual DOM, which improves UI rendering performance. 2. Compared with Vue, React is more flexible but has a steep learning curve, which is suitable for large projects. 3. Compared with Angular, React is lighter, dependent on the community ecology, and suitable for projects that require flexibility.
Demystifying React in HTML: How It All WorksApr 17, 2025 am 12:21 AMReact operates in HTML via virtual DOM. 1) React uses JSX syntax to write HTML-like structures. 2) Virtual DOM management UI update, efficient rendering through Diffing algorithm. 3) Use ReactDOM.render() to render the component to the real DOM. 4) Optimization and best practices include using React.memo and component splitting to improve performance and maintainability.
React in Action: Examples of Real-World ApplicationsApr 17, 2025 am 12:20 AMReact is widely used in e-commerce, social media and data visualization. 1) E-commerce platforms use React to build shopping cart components, use useState to manage state, onClick to process events, and map function to render lists. 2) Social media applications interact with the API through useEffect to display dynamic content. 3) Data visualization uses react-chartjs-2 library to render charts, and component design is easy to embed applications.
Frontend Architecture with React: Best PracticesApr 17, 2025 am 12:10 AMBest practices for React front-end architecture include: 1. Component design and reuse: design a single responsibility, easy to understand and test components to achieve high reuse. 2. State management: Use useState, useReducer, ContextAPI or Redux/MobX to manage state to avoid excessive complexity. 3. Performance optimization: Optimize performance through React.memo, useCallback, useMemo and other methods to find the balance point. 4. Code organization and modularity: Organize code according to functional modules to improve manageability and maintainability. 5. Testing and Quality Assurance: Testing with Jest and ReactTestingLibrary to ensure the quality and reliability of the code
React Inside HTML: Integrating JavaScript for Dynamic Web PagesApr 16, 2025 am 12:06 AMTo integrate React into HTML, follow these steps: 1. Introduce React and ReactDOM in HTML files. 2. Define a React component. 3. Render the component into HTML elements using ReactDOM. Through these steps, static HTML pages can be transformed into dynamic, interactive experiences.
The Benefits of React: Performance, Reusability, and MoreApr 15, 2025 am 12:05 AMReact’s popularity includes its performance optimization, component reuse and a rich ecosystem. 1. Performance optimization achieves efficient updates through virtual DOM and diffing mechanisms. 2. Component Reuse Reduces duplicate code by reusable components. 3. Rich ecosystem and one-way data flow enhance the development experience.
React: Creating Dynamic and Interactive User InterfacesApr 14, 2025 am 12:08 AMReact is the tool of choice for building dynamic and interactive user interfaces. 1) Componentization and JSX make UI splitting and reusing simple. 2) State management is implemented through the useState hook to trigger UI updates. 3) The event processing mechanism responds to user interaction and improves user experience.
