React vs Angular
React vs Angular
一句话：React 是库（只管视图，其他自己选）； Angular 是框架（路由、HTTP、表单、依赖注入、 测试全都自带）。
| React | Angular | |
|---|---|---|
| 定位 | 库 | 全套框架 |
| 语言 | JS / TS，JSX | TypeScript 强制，HTML 模板 |
| 数据流 | 单向 | 支持双向绑定（ngModel） |
| DOM 策略 | 虚拟 DOM | 增量 DOM + 变更检测 |
| 学习曲线 | 入门低，但选型多 | 入门陡（DI、RxJS、装饰器），之后规范统一 |
| 适合 | 灵活、迭代快、团队愿意自己搭 | 大型企业项目、要求统一规范 |
怎么答得体面：别踩一捧一。说 「React 给自由也给选型负担， Angular 给约定也给学习成本；小而快的项目和需要长期多人维护的大项目， 答案不一样」。
会追问 Vue—— Vue 在两者之间：有官方路由和状态库 （比 React 统一）， 但比 Angular 轻；模板语法上手快。
In one line: React is a library (it handles the view, you choose the rest); Angular is a framework (routing, HTTP, forms, dependency injection and testing all come in the box).
| React | Angular | |
|---|---|---|
| What it is | A library | A full framework |
| Language | JS / TS, JSX | TypeScript required, HTML templates |
| Data flow | One-way | Two-way binding available (ngModel) |
| DOM strategy | Virtual DOM | Incremental DOM + change detection |
| Learning curve | Easy to start, but many choices to make | Steep at first (DI, RxJS, decorators), consistent after |
| Fits | Flexible work, fast iteration, a team happy to assemble its own stack | Large enterprise projects that need one standard |
How to answer without picking a fight: do not talk one down to lift the other. Say “React gives you freedom and the burden of choosing; Angular gives you conventions and a learning cost. The answer differs for a small fast project and for a big one many people maintain for years.”
They will ask about Vue — Vue sits between the two: it has an official router and state library (more unified than React) but stays lighter than Angular, and the template syntax is quick to pick up.
