What should I do if the teacher forgets about JavaScript?
In the process of learning programming, we often encounter the problem of forgetting the knowledge points taught. Of course, for many beginners, this situation is normal. Especially in the process of self-study, these problems often cannot be solved in time, and these problems may appear repeatedly, seriously affecting the learning effect.
Among them, JavaScript is the most important language in Web front-end development, which provides interactivity and dynamic functions for websites and applications. If you encounter a situation where you forget how to learn JavaScript, you can start from the following aspects:
1. Recall the basic syntax of JavaScript
The basic syntax of JavaScript is the key to writing any code. Returning to the basics, it is very necessary to review the basic syntax of JavaScript. For example, variables and data types, without the correct variables and data types you will not be able to write code successfully. In addition, JavaScript also has flow control statements, such as if statements, loop statements, function calls, etc.
If you don’t remember these basic grammar, you can try to follow videos, articles and other learning materials, especially to consolidate them in practice.
2. Check the official documentation
If you forget a function or method in JavaScript, you can check the official JavaScript documentation to find the corresponding solution. As you review these documents, you can become familiar with the syntax of each function and related concepts. In addition, the official documentation also provides practical examples from which you can learn how to use JavaScript.
3. Online learning platform
If you need to further learn JavaScript, you can register for online learning platforms, such as Udemy, Coursera, and edx, and find JavaScript-related online courses. The great thing about these courses is that you can follow instructional videos to review topics and apply the new JavaScript language in your exercises. Some courses are also interactive, allowing you to take on coding challenges to reinforce each point.
4. Participate in community activities
The programming community is an excellent place to learn and develop skills. In these communities, you can interact with people who are also good at programming and gain a deeper understanding of JavaScript from their experiences and opinions. You can attend local meetings or join discussions via social media. Attending community events can also serve as a landing point to find additional resources and learning materials.
Overall, relearning JavaScript requires a variety of different approaches, including going back to the basics, reviewing relevant documentation, and leveraging online learning platforms and communities for in-depth learning. Sometimes it just takes a little time and patience to take bigger steps on the road to learning programming.

React combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.

React is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent

The 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 components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.

The React ecosystem includes state management libraries (such as Redux), routing libraries (such as ReactRouter), UI component libraries (such as Material-UI), testing tools (such as Jest), and building tools (such as Webpack). These tools work together to help developers develop and maintain applications efficiently, improve code quality and development efficiency.

React is a JavaScript library developed by Meta for building user interfaces, with its core being component development and virtual DOM technology. 1. Component and state management: React manages state through components (functions or classes) and Hooks (such as useState), improving code reusability and maintenance. 2. Virtual DOM and performance optimization: Through virtual DOM, React efficiently updates the real DOM to improve performance. 3. Life cycle and Hooks: Hooks (such as useEffect) allow function components to manage life cycles and perform side-effect operations. 4. Usage example: From basic HelloWorld components to advanced global state management (useContext and

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.

React is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.
