React Native中props特性是否与React存在差异？文档描述存疑
Great question—this is a common point of confusion when interpreting React Native docs, so let's clear this up:
Core Fact: No Difference Between React and React Native Here
First things first: React Native behaves exactly like React in this scenario. A single component instance absolutely can receive different props over its lifecycle without being recreated. For example:
- If a parent component updates its state and passes a new value as a prop to a child component, the child's instance stays intact.
- The child will re-render with the new props, and hooks like
useEffect(if they depend on the updated prop) will trigger accordingly.
What the Official Docs Probably Meant
The line "props are set by the parent and remain fixed throughout the component's lifecycle" is almost certainly a misphrasing. What it's trying to convey is that props themselves are immutable—you shouldn't modify props directly inside a component (you should treat them as read-only). It does not mean that a component instance can't receive new prop values from its parent over time.
Next Steps for Documentation Concerns
If you believe the documentation is misleading, even if you can't submit an official GitHub Issue, you can:
- Bring up the question in React Native community discussion spaces to get feedback from maintainers and experienced developers.
- If you're comfortable, you can even submit a documentation pull request to clarify the wording—small fixes like this are always welcome in open source projects.
