Node.js is a JavaScript runtime based on the Chrome V8 engine. It helps developers build high-performance, scalable web applications, while Visual Studio Code is a free code editor and one of the most popular code editors.
Many people like to use Node.js to write back-end logic, and they also use Visual Studio Code for development. However, when you use Node.js in Visual Studio Code, you may find a tricky problem: you cannot enter commands in the terminal.
The reason for this problem is that the terminal in Visual Studio Code uses PowerShell by default instead of the command prompt, which is often called CMD. Node.js is typically developed and tested interactively using the command prompt and does not support entering commands in PowerShell.
So, how to configure the use of command prompt in Visual Studio Code? Below we will introduce two solutions.
Solution 1: Use external terminal
Visual Studio Code supports the use of external terminals, such as CMD, Git Bash, etc., which can be configured in the settings. The following are the specific steps:
- Open Visual Studio Code;
- Click the "Settings" icon on the left, or use the shortcut key "Ctrl," to open the settings;
- Enter "terminal.integrated.shell.windows" in the search box;
- Click "Edit in settings.json" and change the default settings to "terminal.integrated.shell.windows": "C:\ Windows\System32\cmd.exe";
- Now you can run Node.js commands in an external terminal, such as entering "node -v" to view the current version number of Node.js.
Solution 2: Install and use plug-ins
Visual Studio Code has a large number of plug-ins that can be used to enhance its functionality, and there are also many plug-ins that can help us solve this problem. The following are two popular plug-ins:
- "Code Runner"
This plug-in can run code directly in the editor of Visual Studio Code and supports many programming language. You can install it by typing "code runner" in the terminal.
- "Node.js Exec"
This plug-in allows you to use Node.js in Visual Studio Code and supports entering commands in the terminal, which is very suitable for Node. js development and testing. You can install it by typing "nodejs exec" in the terminal.
Summary
Node.js is a very powerful tool that can help us develop high-performance, scalable web applications. Using Visual Studio Code also makes our development work more efficient and enjoyable. When encountering problems, we should learn to find and solve them. For example, the problem of being unable to enter Node.js commands in Visual Studio Code can be solved by using an external terminal or installing a plug-in. The most important thing is that we must maintain our curiosity and spirit of exploration about new technologies, and continue to learn and improve our skills.

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.
