The node version cannot be downgraded directly, but you can uninstall the higher version and use the nvm version controller to reinstall the lower version of the node to downgrade. Downgrade method: 1. Use "npm instlal -g n" to globally install the n module; 2. Use "n rm version" to uninstall the specified version; 3. After installing nvm, use "nvm use version" to install the specified version.
The operating environment of this article: Windows 10 system, nodejs version 16, Dell G3 computer.
Can node be downgraded?
The node version can be directly upgraded to a higher version, but it cannot be downgraded to a lower version
Some projects require a higher version and some require a lower version , so you can use the version controller nvm
The example is as follows:
1. Install the npm plug-in n and manage the node version through the n module
1 , Globally install n module
npm instlal -g n
2. Install the current stable version
n stable或者sudo n stable
3. Install the latest version
n latest或者sudo n latest
4. Install the specified version of node
n v8.16.0
5. Uninstall the specified node version
n rm v8.16.0
2. Use nvm to manage the node version
1. Install nvm
brew install nvm
2. Use nvm to install the node version
Install the latest version
nvm isntall node
Install the specified version
nvm install 8.16.0
3. View all versions
nvm ls
4. Switch node version
Use the latest version
nvm use node
Use the specified version
nvm use 10.16.2
Knowledge expansion
Some projects require a higher version and some require a lower version, so you can use the version controller nvm ( windows system)
1. First clear and uninstall the local node
cmd input where node to view the node storage location, clear all files in this folder
Control Panel->Uninstall the program->node uninstall
2. Download nvm:Releases · coreybutler/nvm-windows · GitHub
Download nvm-setup.zip
Double-click to install and select the location where nvm and node downloads are stored. The first path is the saving path of nvm, and the second is the path where node is downloaded and saved. It is best not to put it on the c drive
3. Check whether the nvm installation is successful: nvm v
4. Next, install the node version: nvm ls available to view the version. In addition to the following, the rest can also be installed

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.
