Reactjs 是否会将在children.map期间创建的组件重新命名？

如果我有如下设置：

const ChildComponent = React.memo((props) => {
   return (<>...</>);
});

const ParentComponent = (props) => {
   return (
      {React.Children.map(props.children, child => {
         return <div>{child}</div>;
      )}
   );
}

const ChildComponent = React.memo((props) => {
   return (<p>{props.a}</p>);
}, (prev, next) => {
   if (prev.a === next.a) { console.log('memo'); return true; }
   console.log('no memo'); return false;
});

const ParentComponent = (props) => {
   return (
      {React.Children.map(props.children, child => {
         return <div>{child}</div>;
      )}
   );
}

const App = () => {
   return (
      <ParentComponent>
          <ChildComponent a='a'/>
          <ChildComponent a='b'/>
          <ChildComponent a='c'/>
      </ParentComponent>
   );
}

const ChildComponent=React.memo（（道具）=>{
回报率（…）；
});
常量ParentComponent=（道具）=>{
返回(
{React.Children.map（props.Children，child=>{
返回{child}；
)}
);
}

假设

child.props

完全相同，则会将

child

记录下来，还是每次都会重新播放？

将设置更改为以下内容：

const ChildComponent = React.memo((props) => {
   return (<>...</>);
});

const ParentComponent = (props) => {
   return (
      {React.Children.map(props.children, child => {
         return <div>{child}</div>;
      )}
   );
}

const ChildComponent = React.memo((props) => {
   return (<p>{props.a}</p>);
}, (prev, next) => {
   if (prev.a === next.a) { console.log('memo'); return true; }
   console.log('no memo'); return false;
});

const ParentComponent = (props) => {
   return (
      {React.Children.map(props.children, child => {
         return <div>{child}</div>;
      )}
   );
}

const App = () => {
   return (
      <ParentComponent>
          <ChildComponent a='a'/>
          <ChildComponent a='b'/>
          <ChildComponent a='c'/>
      </ParentComponent>
   );
}

const ChildComponent=React.memo（（道具）=>{
返回（{props.a}
）；
}，（上一页，下一页）=>{
if（prev.a==next.a）{console.log（'memo'）；返回true；}
console.log（'no memo'）；返回false；
});
常量ParentComponent=（道具）=>{
返回(
{React.Children.map（props.Children，child=>{
返回{child}；
)}
);
}
常量应用=（）=>{
返回(
);
}

我在控制台中看到了

memo

。无论如何，这似乎不是一个详尽的答案，但我认为这意味着它是有效的
