HTML (Hypertext Markup Language) is the basic language for building Web pages. Adding comments in HTML code can let other developers understand the functions you want to implement and facilitate subsequent maintenance.
HTML comments are usually enclosed in <!-- -->
tags. To quickly add or remove comments, you can try using the following HTML comment shortcuts. These shortcut keys can help you greatly improve your coding efficiency.
- Open comments
It is very common to add comments in the code, and the reverse operation is equally important. To open comments within an HTML code block, you can use the following shortcut keys: ctrl /
.
After pressing ctrl /
, <!--
will be inserted at the beginning of the current line and --> will be inserted at the end of the line.
and include the selected text in the comment. This shortcut key is also very convenient when adding multi-line comments.
- Close comments
In order to close comments in an HTML code block, you can use the following shortcut keys: ctrl shift /
.
This shortcut key can add <!-- /-->
at the beginning of the current line and close the current comment block. If no text is selected, it will close everything within the current comment.
- Jump to comments
Finding comments in HTML files is also a fairly common task. To quickly jump to the next comment, you can use the following shortcut keys: ctrl .
.
After pressing ctrl .
, it will jump to the next comment block. If there are no comments, it will prompt "No comments found".
- Jump to the closing tag
HTML tags usually start with a starting tag (such as ) and an ending tag (such as
). In large HTML files, it's easy to forget where some of the tags end.
The way to quickly jump to the closing tag in HTML code is to use the following shortcut keys: ctrl shift .
.
After pressing this shortcut key, it will jump to the end mark of the current start mark. If there is no unmatched end tag at the current position, "End tag not found" will be prompted.
- Comment the entire line
To comment the entire line, you can use the following shortcut keys: ctrl alt /
.
After pressing this shortcut key, it will add <!--
at the beginning of the current line, -->
at the end of the line, and Comment out everything on the current line.
The above is the introduction of HTML comment shortcut keys. Knowing these shortcuts and using them frequently while coding will help optimize your coding efficiency.

HTML and React can be seamlessly integrated through JSX to build an efficient user interface. 1) Embed HTML elements using JSX, 2) Optimize rendering performance using virtual DOM, 3) Manage and render HTML structures through componentization. This integration method is not only intuitive, but also improves application performance.

React efficiently renders data through state and props, and handles user events through the synthesis event system. 1) Use useState to manage state, such as the counter example. 2) Event processing is implemented by adding functions in JSX, such as button clicks. 3) The key attribute is required to render the list, such as the TodoList component. 4) For form processing, useState and e.preventDefault(), such as Form components.

React interacts with the server through HTTP requests to obtain, send, update and delete data. 1) User operation triggers events, 2) Initiate HTTP requests, 3) Process server responses, 4) Update component status and re-render.

React is a JavaScript library for building user interfaces that improves efficiency through component development and virtual DOM. 1. Components and JSX: Use JSX syntax to define components to enhance code intuitiveness and quality. 2. Virtual DOM and Rendering: Optimize rendering performance through virtual DOM and diff algorithms. 3. State management and Hooks: Hooks such as useState and useEffect simplify state management and side effects handling. 4. Example of usage: From basic forms to advanced global state management, use the ContextAPI. 5. Common errors and debugging: Avoid improper state management and component update problems, and use ReactDevTools to debug. 6. Performance optimization and optimality

React can be embedded in HTML to enhance or completely rewrite traditional HTML pages. 1) The basic steps to using React include adding a root div in HTML and rendering the React component via ReactDOM.render(). 2) More advanced applications include using useState to manage state and implement complex UI interactions such as counters and to-do lists. 3) Optimization and best practices include code segmentation, lazy loading and using React.memo and useMemo to improve performance. Through these methods, developers can leverage the power of React to build dynamic and responsive user interfaces.

React is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.

React's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.
