前端框架迭代快,新特性层出不穷。但翻来覆去就一条主线:数据变了页面怎么跟上。 每个框架都在用不同的方法解决同一个问题。其实,

Vue 的做法是编译阶段分析模板 → 响应式程序追踪数据变化 → 精准更新 DOM。老实说,
React 的做法是组件函数重新执行 → 新旧虚拟 DOM 对比 → 批量更新 DOM。其实,
背了忘、忘了背?不用了,这篇文章不罗列 API,只讲一件事——数据变了页面怎么跟上。看完你就能串起 Vue 和 React 各自的整条链路。
截至 年 月,Vue 稳定版为 .0.16
从 .x 到 .x,refreactivecomputedwatch这套 API 全部互通,不存在 Vue .x 升 Vue .x 时大规模重写的问题
A simple counter example:
vue
function render { return createVNode,createVNode]) }
| 特性 | 描述 |
|---|---|
| Vapor Mode | 把模板直接编译成DOM操作代码,跳过虚拟DOM的创建和diff |
| alien-signals | 底层依赖追踪从Map/Set换成双向链表。仅标记脏状态真正读取时才计算值 |
尤雨溪在 State of Vue.js 中明确表示: "即便未来有 Vue5,也只会极少量的破坏性变更" 团队策略是把大特性消化在 .x 中。

.vue文件里的浏览器不认识,Vue的编译器把它翻译成JS函数,执行这个函数就会生成一棵虚拟DOM树。
再看示例,vue {{name}} HelloWorld!
| Flag | Meaning | Example |
|---|---|---|
| TEXT | Only text content changes | {{message}} |
| CLASS | Only CSS classes change | :class="{active}" |
| STYLE | Only inline styles change | :style="{color}" |
| PROPS | Only prop values change | :id=dynamicId |
Vue采用ES6 Proxy实现响应式:
javascript
function reactive {
return new Proxy(obj,{
get {
track;// "有人读我了,记下来!"
return target;},set {
target = value;// "值改了,通知所有读过我的人!"
trigger,话说回来,return true;}
})
}
✅ 优势精准追踪依赖关系,仅更新受影响组件
❌ 局限Proxy无法监听基本类型,所以需要ref
ref vs reactive:
ref适合基本类型/reactive适合对象。reactive解构会失效。话说回来,Data changes -> Re-render -> Virtual DOM diff -> Update real DOM
✅ Vue's diff algorithm uses compiled patch flags to skip unnecessary checks:
javascript
// Compiled output with patch flags highlighted:
render {
return createVNode(
"div"。null,)
}
Before React Fiber: → Recursive reconciliation
After React Fiber: → Linked list based work scheduling
Problem in React <= v15: • State changes would block browser UI thread for too long • Animations would stutter/jank during complex re-renders
Solution in React>= v16: • Work divided into chunks/fibers • Browser gets control 娱乐ween chunks for painting/UI updates

function App { const =useTransition;return (
{ setValue;startTransition=>filterResults);}} placeholder={"Search..."}/>
{pending&&"
All state updates within event handlers are automatically batched into a single re-render.
Before batching:
handleClick{
setA;setB,setC;// THREE separate renders!}
After batching:
// ONE combined render!}

Performance depends heavily on your app's specific needs.
Use Vue if you want: • Simpler learning curve • Less boilerplate • Stronger type inference • Better performance out-of--box with less tuning required.
Use React if you need: • Larger ecosystem • More customization options • Server components architecture • Mobile development capabilities.
Both frameworks are converging towards similar goals via different paths:
💡 Compilation-Based Optimization: • Vue's Vapor mode removes runtime entirely. • React Compiler performs automatic memoization at compile time.
💡 Signals Standardization: ECMAScript Signals proposal at Stage II will bring framework-independent reactivity primitives.
💡 Convergence Points: Both now have official server-side rendering solutions and are optimizing away from virtual DOM where possible.
✨ Takeaway Message ✨ :
Neir framework is objectively 娱乐ter - y solve slightly different problems in slightly different ways. Your choice should depend on your team's needs and constraints rar than dogmatic preferences about which approach is "correct".
What matters most is understanding trade-offs behind each design decision so you can make informed choices for your specific project requirements.
