jQuery is a well-known JavaScript library, often called a "framework". This title has certain rationality and historical origins.
First of all, jQuery is very powerful and complex, and can easily implement a series of common web development needs such as selecting elements, modifying styles, processing events, sending asynchronous requests, and dynamically creating HTML elements. These function points are encapsulated, easy to be used by developers, and have good compatibility.
However, jQuery is not a complete web development framework. Developers also need to use HTML, CSS, JavaScript and other technology stacks to build a complete web application. Therefore, jQuery is called a "lightweight framework" and can play an important role in applications.
Secondly, when we develop web applications, we usually need to use many different tools and libraries. For example, we may need to use front-end frameworks such as React, Vue, and Angular to build complex user interfaces, and use testing frameworks such as Jasmine or Mocha for unit testing. Among these frameworks and testing tools, jQuery is often used as a basic library. This is because the DOM traversal, event handling, Ajax request and other functions provided by jQuery are widely used in different frameworks and tools.
In addition, as time goes by, jQuery’s community ecosystem gradually improves, and more and more plug-ins and extension libraries are developed, which further expands jQuery’s functions and better meets the needs of developers. . These plug-ins and extension libraries can serve as enhanced versions of jQuery or as independent libraries.
To sum up, although jQuery is not a complete web application framework, it has powerful functions, wide applications, rich community ecology and a long history. It is called a "framework" Quite reasonable.
The above is the detailed content of Why jquery is called a framework. For more information, please follow other related articles on the PHP Chinese website!
React: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AMReact 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.
The Future of React: Trends and Innovations in Web DevelopmentApr 19, 2025 am 12:22 AMReact'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: A Powerful Tool for Building UI ComponentsApr 19, 2025 am 12:22 AMReact is a JavaScript library for building user interfaces. Its core idea is to build UI through componentization. 1. Components are the basic unit of React, encapsulating UI logic and styles. 2. Virtual DOM and state management are the key to component work, and state is updated through setState. 3. The life cycle includes three stages: mount, update and uninstall. The performance can be optimized using reasonably. 4. Use useState and ContextAPI to manage state, improve component reusability and global state management. 5. Common errors include improper status updates and performance issues, which can be debugged through ReactDevTools. 6. Performance optimization suggestions include using memo, avoiding unnecessary re-rendering, and using us
Using React with HTML: Rendering Components and DataApr 19, 2025 am 12:19 AMUsing HTML to render components and data in React can be achieved through the following steps: Using JSX syntax: React uses JSX syntax to embed HTML structures into JavaScript code, and operates the DOM after compilation. Components are combined with HTML: React components pass data through props and dynamically generate HTML content, such as. Data flow management: React's data flow is one-way, passed from the parent component to the child component, ensuring that the data flow is controllable, such as App components passing name to Greeting. Basic usage example: Use map function to render a list, you need to add a key attribute, such as rendering a fruit list. Advanced usage example: Use the useState hook to manage state and implement dynamics
React's Purpose: Building Single-Page Applications (SPAs)Apr 19, 2025 am 12:06 AMReact is the preferred tool for building single-page applications (SPAs) because it provides efficient and flexible ways to build user interfaces. 1) Component development: Split complex UI into independent and reusable parts to improve maintainability and reusability. 2) Virtual DOM: Optimize rendering performance by comparing the differences between virtual DOM and actual DOM. 3) State management: manage data flow through state and attributes to ensure data consistency and predictability.
React: The Power of a JavaScript Library for Web DevelopmentApr 18, 2025 am 12:25 AMReact 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 Ecosystem: Libraries, Tools, and Best PracticesApr 18, 2025 am 12:23 AMThe 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 and Frontend Development: A Comprehensive OverviewApr 18, 2025 am 12:23 AMReact is a JavaScript library developed by Facebook for building user interfaces. 1. It adopts componentized and virtual DOM technology to improve the efficiency and performance of UI development. 2. The core concepts of React include componentization, state management (such as useState and useEffect) and the working principle of virtual DOM. 3. In practical applications, React supports from basic component rendering to advanced asynchronous data processing. 4. Common errors such as forgetting to add key attributes or incorrect status updates can be debugged through ReactDevTools and logs. 5. Performance optimization and best practices include using React.memo, code segmentation and keeping code readable and maintaining dependability
