1. Differences in core design concepts
The underlying implementation of component form
- Vue: After the component is compiled,Object containing render/setup method(Convert SFC to an object via vue-loader or @vitejs/plugin-vue).
-
React: The essence of the component isfunction(function component) or class (class component), JSX will be compiled into Babel
Called.
Compilation Differences between Template and JSX
- Vue: Template will be optimized toTraceable dependencies rendering functions, achieve targeted updates through static analysis.
-
React: JSX compiles into pure JavaScript function calls, relying on developers to manually optimize (such as
）。
2. Implementation of responsive system
| Dimension | Vue | React |
|---|---|---|
| Data binding | Responsive system based on Proxy/, automatically tracking dependencies | Immutable data stream based on state (State) needs to be triggered manually |
| Update granularity | Component-level + attribute-level targeted updates (optimized by Block Tree for virtual DOM) | Component-level update (default full Diff, relying on Fiber scheduling optimization) |
| Trigger method | Responsive data changes automatically trigger rendering | You need to call the setState or Hooks function to trigger the update |
3. Virtual DOM and Diff algorithms
Vue's targeted update
Tag dynamic nodes at compile time (e.g.{{ count }}), Diff only compares the dynamic part.
Example:
<!-- Generate after compilation Block mark -->
<h1>countThe value is: {{ count }}</h1>React's Fiber Architecture
- Split the Diff process into interruptable time slices, prioritizing high-priority tasks (such as animations).
- Full Diff, but incremental update is achieved through the Fiber linked list structure.
4. The evolution of functional programming
| frame | plan | Low-level implementation differences |
|---|---|---|
| Vue | Composition API | The setup function based on responsive system, relying on closure management status |
| React | Hooks | Relying on the linked list structure to maintain the state order, requiring the Hooks call order to be stable |
5. Compilation time optimization comparison
| Optimization strategy | Vue | React |
|---|---|---|
| Static boost | Extract static nodes as constants | No native support |
| Tree structure optimization | Block Tree Reduces Diff Range | Rely on developers to optimize manually |
| Pre-string | Compile static HTML into string constants | Not supported |
Summarize
Similarities: Virtual DOM, componentization, and support functional programming.
Core Differences：
- Vue is implemented through compile-time optimization + responsive systemFine-grained update, React depends on runtime scheduling (Fiber) implementationControllable update priority。
- Vue'sProgressive designLower the threshold for getting started, ReactFunctional conceptProvides greater flexibility.
The above is personal experience. I hope you can give you a reference and I hope you can support me more.
