Vue-与-React-两大前端框架的性能较量-性能对比 (vue与angular以及react的区别)
Loading Speed
React
- Initial Load: React uses Virtual DOM (VirtualDOM) technology, which allows it to perform efficient re-renders by comparing the differences between the Virtual DOM tree and the actual DOM tree. This makes React relatively fast on initial load, as it only updates the parts that need to be modified.
- Route Lazy Loading: React supports route lazy loading, which means it loads components on-demand, reducing the initial load time and dynamically loading other components as needed.
Vue
- Initial Load: Vue uses a progressive enhancement design philosophy, which allows it to load various features and functionalities on demand, resulting in faster initial load speeds.
- Component-level Lazy Loading: Vue's async components and route lazy loading feature enable the delayed loading of certain components, improving initial load speed.
Runtime Performance
React
- Virtual DOM Optimization: React efficiently re-renders by comparing the differences in the Virtual DOM tree, reducing the number of actual DOM manipulations and improving performance.
- Component-level Update Control: React utilizes a component-level state management mechanism that allows more precise control over component updates, avoiding unnecessary re-renders.
Vue
- Reactive System: Vue employs a reactive system to track data changes and performs efficient updates through dependency tracking, updating only the changed parts.
- Template Compilation: Vue compiles templates into render functions at runtime, eliminating the overhead of parsing templates and enhancing performance.
Memory Footprint
React
- Virtual DOM Overhead: Since React uses Virtual DOM technology, it requires additional memory to store the Virtual DOM tree and compare differences, potentially leading to a slight increase in memory footprint.
- Component State Management: React's state management mechanisms (such as Redux) may introduce some memory overhead, especially when dealing with large applications.
Vue
- Lightweight Design: Vue follows a progressive enhancement design approach, loading only the necessary features and functionalities, reducing unnecessary memory consumption.
- Component-level State Management: Vue's reactive system allows more precise tracking of component state changes, reducing unnecessary memory overhead.
Performance Optimization Strategies
React
- Use the `shouldComponentUpdate` lifecycle method to control the conditions for component updates, avoiding unnecessary re-renders.
- Utilize `React.memo` or `React.PureComponent` to cache components, preventing redundant rendering.
- Employ an appropriate state management library (such as Redux) to centralize the management of application state, improving performance and maintainability.
Vue
- Use `v-if` and `v-show` to conditionally render components, reducing unnecessary DOM manipulations.
- Leverage Vue Router's lazy loading feature to load route components on demand.
- Judicious use of computed properties and watch listeners to avoid unnecessary calculations and updates.
Conclusion
In terms of loading speed, both React and Vue have their strengths. React leverages Virtual DOM technology and route lazy loading to enhance initial load speed, while Vue implements faster initial loading through progressive enhancement and component-level lazy loading. In terms of runtime performance, React and Vue employ optimization techniques, such as Virtual DOM or reactive systems, to boost performance. When it comes to memory footprint, Vue stands out as more lightweight, consuming less memory than React. To further optimize performance, developers can adopt appropriate optimization strategies based on their specific requirements.react和vue的区别及优缺点
VUE 与 React 区别:
React 的思路是 HTML in JavaScript 也可以说是 All in JavaScript,通过 JavaScript 来生成 HTML,所以设计了 JSX 语法,还有通过 JS 来操作 CSS,社区的styled-component、JSS等。
而Vue 是把 HTML,CSS,JavaScript 组合到一起,用各自的处理方式,Vue 有单文件组件,可以把 HTML、CSS、JS 写到一个文件中,HTML 提供了模板引擎来处理。
React的优缺点:
灵活性和响应性:它提供最大的灵活性和响应能力。
丰富的JavaScript库:来自世界各地的贡献者正在努力添加更多功能。
可扩展性:由于其灵活的结构和可扩展性,React已被证明对大型应用程序更好。
不断发展:React得到了Facebook专业开发人员的支持,他们不断寻找改进方法。
Web或移动平台:React提供React Native平台,可通过相同的React组件模型为iOS和Android开发本机呈现的应用程序。
Vue的优缺点:
易于使用包含基于HTML的标准模板,可以更轻松地使用和修改现有应用程序。
更顺畅的集成:无论是单页应用程序还是复杂的Web界面,都可以更平滑地集成更小的部件,而不会对整个系统产生任何影响。
更好的性能,更小的尺寸:它占用更少的空间,并且往往比其他框架提供更好的性能。
精心编写的文档:通过详细的文档提供简单的学习曲线,无需额外的知识; HTML和JavaScript将完成工作。
适应性:整体声音设计和架构使其成为一种流行的JavaScript框架。它提供无障碍的迁移,简单有效的结构和可重用的模板。

vue和react哪个更好用,为什么?
Vue和React都是属于目前比较主流的前端框架,实际开发中也经常会拿Vue和React来比较。但是我们通常会根据各自优势来选择项目比较适合的框架。
React优点:
1.声明式设计 −React采用声明范式,可以轻松描述应用。
2.高效 −React通过对DOM的模拟,最大限度地减少与DOM的交互。
3.灵活 −React可以与已知的库或框架很好地配合。
− JSX 是 JavaScript 语法的扩展。React 开发不一定使用 JSX ,但我们建议使用它。
5.组件 − 通过 React 构建组件,使得代码更加容易得到复用,能够很好的应用在大项目的开发中。
6.单向响应的数据流 − React 实现了单向响应的数据流,从而减少了重复代码,这也是它为什么比传统数据绑定更简单。
Vue优点:
1.简单易学,容易上手,Vue是国内团队开发,文档手册比较齐全,很适合前端新手小白学习。
2.更顺畅的集成:无论是单页应用程序还是复杂的Web界面,都可以更平滑地集成更小的部件,而不会对整个系统产生任何影响。
3.性能优势,更小的尺寸:它占用更少的空间,并且往往比其他框架提供更好的性能。
精心编写的文档:通过详细的文档提供简单的学习曲线,无需额外的知识; HTML和JavaScript将完成工作。
4.运行速度快,相对于React来说,性能着一方面Vue占有绝大优势。
根据不同框架优点,我们在实际项目开发选型中一般中小型项目我们会选择使用Vue,大型项目会选择React。
