How to turn off JavaScript in mobile QQ browser
In today's era of digital penetration, mobile Internet has become an indispensable part of people's work, study, and entertainment. Among them, QQ Browser can be said to be the leader among many browsers. It is deeply loved by the public because of its simple operation and fast loading speed. However, some people have encountered a headache when using QQ Browser - pop-up advertisements or unnecessary pop-ups on web pages keep appearing. This situation is often related to JavaScript scripts, and QQ Browser also provides the option to turn off JavaScript. This article will introduce the methods and functions of turning off JavaScript from the following aspects.
1. The role of JavaScript script
JavaScript, usually abbreviated as JS, is a high-level programming language. It is widely used in Web front-end development to provide dynamic effects for web pages, such as form validation. , image carousel, dynamic update page, etc. The JavaScript language interpreter can be directly embedded in web pages, and combined with HTML and CSS languages, to achieve web page interaction effects. Advertisers use JavaScript technology to embed advertising scripts into web pages to achieve pop-up ads and other services. Therefore, changing a webpage that runs smoothly on a website to one without JS will have a huge impact on some websites.
2. The significance of turning off JavaScript

At this time, turning off JavaScript can not only protect user privacy, but also reduce web page loading time and improve the speed of entire web browsing.
3. How to turn off JavaScript in QQ Browser
QQ Browser is a browser based on the Webkit kernel and has perfect support for JavaScript scripts. Enabling or disabling JavaScript is easy, just click on the browser settings and then find the JavaScript switch button in the browsing options bar.
The steps are as follows:
1. Open the QQ browser, click the three vertical dots in the upper right corner, and enter the browser settings.
2. Find the "Browsing Options" column in the settings interface and click the JavaScript button inside to turn the JavaScript function on or off.
3. After turning it on/off, re-enter the corresponding website to experience different web page effects.
It is worth noting that after turning off JavaScript, some website functions may be restricted, so you need to make a choice based on the actual situation.
4. Possible problems after turning off JavaScript
After turning off JavaScript, because the browser no longer interprets the JavaScript script in the web page, some functions of some web pages will be restricted or invalid, such as the picture wheel. broadcast, form submission, etc. In addition, some users are accustomed to turning off JavaScript, resulting in the excellent dynamic effects and information push in the web page being unable to be displayed, affecting the user experience.
5. Summary
JavaScript plays an important role in modern web development, but it has also been abused by malicious elements. When using QQ Browser, you can turn on or off the JavaScript option according to the actual situation to achieve a better web browsing experience. In our daily use, we should also strengthen our awareness of security and not easily click on links in text messages, emails, and social media to avoid personal information being attacked by bad advertisements.

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

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.

React is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.

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.

TypeScript enhances React development by providing type safety, improving code quality, and offering better IDE support, thus reducing errors and improving maintainability.

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.

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.
