Has WeChat banned javascript?
Recent news said that WeChat announced that it will ban the use of Javascript after January 1, 2021.
Javascript is a language that allows developers to interact with each other on web pages and achieve dynamic effects. Since its birth in 1995, it has become an integral part of web development.
However, WeChat recently officially stated that it would ban the use of Javascript, which has aroused widespread attention and heated discussion. Some people say that doing so will affect the work of a large number of developers, but others believe that this is an effective means to alleviate WeChat network security problems.
In fact, Javascript, as a scripting language, is used far beyond web development. In daily use, we often encounter situations where it is used. For example, when we use mini programs on WeChat, we need to use Javascript for development.
So why does WeChat ban Javascript? The author believes that this is mainly due to network security considerations.
In the current Internet environment, network security has become a global problem. Various hacker attacks and online frauds emerge in endlessly, and a large number of personal and institutional data have suffered varying degrees of losses. WeChat’s ban on Javascript is actually to strengthen its own network security defense measures.
The characteristics of the Javascript language determine that it has some security flaws. For example, it can directly access the user's cookie, or send requests to the outside without the user's knowledge. These operations can be used by criminals to carry out network attacks. Disabling Javascript can avoid these security holes to the greatest extent.
Of course, WeChat’s ban on Javascript also means that some web developers need to relearn new programming languages or find other platforms for development. However, this also brings opportunities to these developers, who can continuously improve their comprehensive capabilities by learning new programming skills.
In addition, WeChat’s ban on Javascript has also increased cooperation between developers and application developers. Through closer collaboration, more innovations can be discovered and more secure and practical products can be created.
In short, although WeChat’s ban on Javascript will cause inconvenience to some developers, it is also to better protect users’ information security and contribute to the cause of network security. In this era where the Internet security situation is becoming increasingly severe, we need to work together to contribute to the cause of network security and create a more prosperous and secure Internet environment.

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.

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 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 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'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.

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 main functions include componentized thinking, state management and virtual DOM. 1) The idea of componentization allows splitting the UI into reusable parts to improve code readability and maintainability. 2) State management manages dynamic data through state and props, and changes trigger UI updates. 3) Virtual DOM optimization performance, update the UI through the calculation of the minimum operation of DOM replica in memory.
