The core difference between React and Vue in responsive mechanisms is mainly reflected inData change detection method、Update trigger logicandDesign conceptThe above, the details are as follows:
1. Data change detection method
Vue's responsiveness
principle:passProxy(Vue3) or(Vue2) Hijack data and automatically track dependencies.
Features：
- When data is modifiedAutomatically trigger updates, no manual notification is required (such as directly modifying array elements or object properties to trigger view updates).
- supportFine-grained update, re-render only components that depend on changes.
React's responsiveness
principle:based onImmutable data,passsetStateoruseStateExplicitly trigger updates, relying on the virtual DOM's Diff algorithm to update batches.
Features：
- Data changes are requiredManually call the update method(like
setCount), determine the update range through comparison between old and new virtual DOMs. - By default, the current component and its subcomponents need to be rerendered.
oruseMemoManual optimization.
2. Update trigger logic
| characteristic | Vue | React |
|---|---|---|
| Dependency collection | Automatic collection (via responsive system) | Need to be managed manually (such as relying on arrays) |
| Update range | Update only components that depend on changes | Re-render components and subcomponents by default |
| Performance optimization | Built-in fine-grained updates (such as Patch Flags) | Rely on developer manual optimization (such as shouldComponentUpdate) |
| Array/Object Modification | Direct modification will automatically trigger updates | Need to return a new reference (such as [...arr]) |
3. Differences in design concepts
- Vue:passBuilt-in responsive systemLower development thresholds and emphasizeDeclarativeandAutomatic optimization(such as static boosts when template compilation).
- React:emphasizeFunctional programmingandExplicit control, more flexibility but developers need to deal with more details (such as state improvement, performance optimization).
4. Performance optimization strategy
Vue：
- Reduce unnecessary rendering by relying on collecting precise positioning changes.
- Template compilation-time optimization (such as static node promotion).
React：
- Diff algorithm and Fiber architecture shard updates relying on virtual DOM.
- Optimize rendering performance with Time Slicing and priority scheduling.
Summarize
- Vue is suitable: Rapid development, small and medium-sized projects, hoping to reduce manual optimization scenarios.
- React suitable: Scenarios where large and complex applications require high control over update logic.
The above is personal experience. I hope you can give you a reference and I hope you can support me more.
