With the continuous advancement of Internet technology, front-end development has been regarded as an important part of the development of Web technology. As one of the most important tools in front-end development, jQuery is more simplified and efficient than native JavaScript and is widely used in development.
So, what’s so good about jQuery?
- Unique selector makes developers more convenient
Compared with native JavaScript, jQuery has a more powerful and smart selector function. Only a $ sign plus a selector is needed to reference the element, so you don't have to worry about misoperations caused by the same element name. There are many types of selectors. In addition to the basic id and class selectors, there are also attribute, sub-element, pseudo-class selectors, etc., which are very flexible to use. Moreover, jQuery can use CSS3 selector specifications to make selecting elements easier and faster.
- Rich API, powerful functions
In addition to selectors, jQuery also provides a very rich and powerful API. Its API can help developers easily complete development work such as event binding, obtaining DOM element information, dynamically adding, deleting, modifying nodes, animation effects, etc. Compared with native JavaScript, it reduces the amount and complexity of developers' code, greatly improves development efficiency, and allows developers to focus more on business issues rather than DOM operation issues.
- Strong compatibility, more assured development
With the continuous development of Web technology, different browsers have different restrictions on supporting certain Web standards. This Often becomes a big problem for front-end developers. jQuery is like an adapter, it can automatically adapt between different browser platforms, ensuring consistency and compatibility on various browsers. This means that developers do not need to consider the compatibility of other platforms and focus more on the implementation of business logic.
- The development community is active and the ecosystem is complete
jQuery has strong community support. Developers can easily find some excellent open source plug-ins and programs, all of which are developed by Written and shared by passionate developers. These plug-ins allow developers to quickly expand functionality during the development process without having to write repeated code.
- Superior performance and doubled efficiency
In order to optimize performance, jQuery uses a variety of strategies to minimize the number of DOM operations, such as object caching mechanism and chain calls. This can greatly improve performance and efficiency, allowing developers to develop efficient web applications faster.
In summary, jQuery is simple, efficient, easy to use, highly compatible, and has a strong development community, excellent ecology, and rich APIs, all of which make it indispensable in front-end development. One of the tools. This is why more and more developers trust and use jQuery.

React vs. Backend Frameworks: A ComparisonApr 13, 2025 am 12:06 AMReact 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.
HTML and React: The Relationship Between Markup and ComponentsApr 12, 2025 am 12:03 AMThe relationship between HTML and React is the core of front-end development, and they jointly build the user interface of modern web applications. 1) HTML defines the content structure and semantics, and React builds a dynamic interface through componentization. 2) React components use JSX syntax to embed HTML to achieve intelligent rendering. 3) Component life cycle manages HTML rendering and updates dynamically according to state and attributes. 4) Use components to optimize HTML structure and improve maintainability. 5) Performance optimization includes avoiding unnecessary rendering, using key attributes, and keeping the component single responsibility.
React and the Frontend: Building Interactive ExperiencesApr 11, 2025 am 12:02 AMReact 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 and the Frontend Stack: The Tools and TechnologiesApr 10, 2025 am 09:34 AMReact 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.
React's Role in HTML: Enhancing User ExperienceApr 09, 2025 am 12:11 AMReact 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 Components: Creating Reusable Elements in HTMLApr 08, 2025 pm 05:53 PMReact 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 Strict Mode PurposeApr 02, 2025 pm 05:51 PMReact Strict Mode is a development tool that highlights potential issues in React applications by activating additional checks and warnings. It helps identify legacy code, unsafe lifecycles, and side effects, encouraging modern React practices.
React Fragments UsageApr 02, 2025 pm 05:50 PMReact Fragments allow grouping children without extra DOM nodes, enhancing structure, performance, and accessibility. They support keys for efficient list rendering.
