Reasons: 1. IE8 and below versions do not support the Object.defineProperty method, but this is necessary for Vue to implement responsiveness, so judging from the source code of Vue, it cannot support IE8 at all; 2. Vue needs Supports Promise support, IE8 does not support Promsie.
Look at the official website of Vue to see why IE8 is not supported
Vue.js will implement two-way for all For bound data, use Object.defineProperty to convert all these properties into getters/setters. Object.defineProperty is a feature in ES5 that cannot be shimmed, which is why Vue does not support IE8 and lower browsers.
Note here: Object.defineProperty is a method that cannot be implemented through the underlay and is related to the browser itself, so Vue fundamentally cannot support IE8;
Vue does not support IE8 and below because Vue uses ECMAScript 5 features that IE8 cannot emulate. But it supports all browsers that are compatible with ECMAScript 5
Moreover, Vue needs to support Promise support, and IE8 also does not support Promsie.
Extended information:
Object.defineProperty()
This method allows precise addition or modification of the properties of the object. Generally, we add properties to objects by assigning values to create and display them in the property enumeration (for...in or Object.keys method), but the property values added in this way can be changed or deleted. Using Object.defineProperty() allows changing the default settings for these additional details. For example, by default, property values added using Object.defineProperty() are immutable.
Search for "Object.defineProperty" in the vue source code:
You can see that there are 5 matching places, which means there are 5 places in vue "Object.defineProperty()" is used.
The version searched is: Vue.js v1.0.26
Browser support for Object.defineProperty():
Yes It can be seen that the support is IE9 and above.

Vue.js vs. React: Scalability and MaintainabilityMay 10, 2025 am 12:24 AMVue.js and React each have their own advantages in scalability and maintainability. 1) Vue.js is easy to use and is suitable for small projects. The Composition API improves the maintainability of large projects. 2) React is suitable for large and complex projects, with Hooks and virtual DOM improving performance and maintainability, but the learning curve is steeper.
The Future of Vue.js and React: Trends and PredictionsMay 09, 2025 am 12:12 AMThe future trends and forecasts of Vue.js and React are: 1) Vue.js will be widely used in enterprise-level applications and have made breakthroughs in server-side rendering and static site generation; 2) React will innovate in server components and data acquisition, and further optimize the concurrency model.
Netflix's Frontend: A Deep Dive into Its Technology StackMay 08, 2025 am 12:11 AMNetflix's front-end technology stack is mainly based on React and Redux. 1.React is used to build high-performance single-page applications, and improves code reusability and maintenance through component development. 2. Redux is used for state management to ensure that state changes are predictable and traceable. 3. The toolchain includes Webpack, Babel, Jest and Enzyme to ensure code quality and performance. 4. Performance optimization is achieved through code segmentation, lazy loading and server-side rendering to improve user experience.
Vue.js and the Frontend: Building Interactive User InterfacesMay 06, 2025 am 12:02 AMVue.js is a progressive framework suitable for building highly interactive user interfaces. Its core functions include responsive systems, component development and routing management. 1) The responsive system realizes data monitoring through Object.defineProperty or Proxy, and automatically updates the interface. 2) Component development allows the interface to be split into reusable modules. 3) VueRouter supports single-page applications to improve user experience.
What are the disadvantages of VueJs?May 05, 2025 am 12:06 AMThe main disadvantages of Vue.js include: 1. The ecosystem is relatively new, and third-party libraries and tools are not as rich as other frameworks; 2. The learning curve becomes steep in complex functions; 3. Community support and resources are not as extensive as React and Angular; 4. Performance problems may be encountered in large applications; 5. Version upgrades and compatibility challenges are greater.
Netflix: Unveiling Its Frontend FrameworksMay 04, 2025 am 12:16 AMNetflix uses React as its front-end framework. 1.React's component development and virtual DOM mechanism improve performance and development efficiency. 2. Use Webpack and Babel to optimize code construction and deployment. 3. Use code segmentation, server-side rendering and caching strategies for performance optimization.
Frontend Development with Vue.js: Advantages and TechniquesMay 03, 2025 am 12:02 AMReasons for Vue.js' popularity include simplicity and easy learning, flexibility and high performance. 1) Its progressive framework design is suitable for beginners to learn step by step. 2) Component-based development improves code maintainability and team collaboration efficiency. 3) Responsive systems and virtual DOM improve rendering performance.
Vue.js vs. React: Ease of Use and Learning CurveMay 02, 2025 am 12:13 AMVue.js is easier to use and has a smooth learning curve, which is suitable for beginners; React has a steeper learning curve, but has strong flexibility, which is suitable for experienced developers. 1.Vue.js is easy to get started with through simple data binding and progressive design. 2.React requires understanding of virtual DOM and JSX, but provides higher flexibility and performance advantages.
