Javascript is not a framework, but a scripting language. JavaScript, referred to as js, is a lightweight, interpreted or just-in-time compiled scripting language with function priority. It is a programming language widely used on the client. It is often used to add a variety of dynamic functions to web pages. Provide users with a smoother and more beautiful browsing effect.

Javascript is not a framework, but a scripting language.
JavaScript ("JS" for short) is a lightweight, interpreted or just-in-time compiled scripting language with function priority. Although it is famous as a scripting language for developing Web pages, it is also used in many non-browser environments. JavaScript is based on prototype programming, a multi-paradigm dynamic scripting language, and supports object-oriented, imperative, declarative, and functional programming paradigm.
JavaScript is a network scripting language that has been widely used in Web application development. It is often used to add various dynamic functions to web pages to provide users with smoother and more beautiful browsing effects. Usually JavaScript scripts realize their functions by embedding them in HTML.
JavaScript can be used in various fields of Web development, such as:
Web application development: The web pages we browse in daily life are It is composed of HTML, CSS, and JavaScript. Through JavaScript, the style of elements in the web page can be updated in real time, and the interaction between people and the web page can be realized (such as monitoring whether the user clicks the mouse or presses a certain button, etc.), and can also Add some cool animations to web pages;
Mobile application development: In addition to web application development, JavaScript can also be used to develop applications on mobile phones or tablets, and We can also use some excellent frameworks (such as React Native) to make development easier;
Web games: Those small games we have played on the web can all be played using JavaScript. Implementation;
Back-end Web application development: In the past, we used JavaScript to develop the front-end part of Web applications, but with the emergence of Node.JS (a JavaScript runtime environment) , so that JavaScript can also be used to develop the back-end part of web applications.
Extended knowledge: JavaScript framework
Javascript framework refers to a programming framework based on the Javascript language.
JavaScript frameworks are application frameworks that allow developer code to quickly leverage off-the-shelf code to meet their unique requirements.
Web application development is similar to building a house. You have the option to create everything from scratch using building materials. But this wastes time and can result in high costs.
However, if you use readily available materials (such as bricks) and assemble them according to the building structure, construction will be faster, saving money and time.
Application development works similarly. Instead of writing every piece of code from scratch, you can use pre-written code based on your application architecture as building blocks. Frames adapt website designs faster and make them easier to use with JavaScript.

13. Meteor.js
Meteor is an open source JS framework released in 2012. It allows you to seamlessly build full-stack applications for mobile, desktop and web.
14. MithrilJS
Although not as popular as other projects on this list, Mithril is an advanced client-side JS framework for developing client-side applications. It is lightweight (less than 10kb gzip) yet fast and provides XHR and routing utilities.
15. ExpressJS
Express.js is a back-end JS framework for developing web applications. It was released as free open source software in 2010 under MIT Aroma.
This is a fast and minimalist Node.js web framework with a range of useful features.
Some Useful JavaScript Tools:
-
#Slick
Slick is a useful JS tool for your carousel needs. Its containers are responsive and scalable. Its features include CSS3 support, sliding, mouse dragging, full accessibility, infinite loop, autoplay, lazy loading, and more.
-
Babel
Babel is a free and open source JS compiler that can be used to convert new JS features to run older JS standards. The plugin is also used for syntax conversions not supported by older versions. It provides polyfills to support missing functionality in some JS environments.
-

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

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 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

The application of React in HTML improves the efficiency and flexibility of web development through componentization and virtual DOM. 1) React componentization idea breaks down the UI into reusable units to simplify management. 2) Virtual DOM optimization performance, minimize DOM operations through diffing algorithm. 3) JSX syntax allows writing HTML in JavaScript to improve development efficiency. 4) Use the useState hook to manage state and realize dynamic content updates. 5) Optimization strategies include using React.memo and useCallback to reduce unnecessary rendering.

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.

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 a JavaScript library for building user interfaces, suitable for large and complex applications. 1. The core of React is componentization and virtual DOM, which improves UI rendering performance. 2. Compared with Vue, React is more flexible but has a steep learning curve, which is suitable for large projects. 3. Compared with Angular, React is lighter, dependent on the community ecology, and suitable for projects that require flexibility.

React operates in HTML via virtual DOM. 1) React uses JSX syntax to write HTML-like structures. 2) Virtual DOM management UI update, efficient rendering through Diffing algorithm. 3) Use ReactDOM.render() to render the component to the real DOM. 4) Optimization and best practices include using React.memo and component splitting to improve performance and maintainability.
