我尝试使用 map 函数在 react-hooks useState 中循环我的列表数据，但我遇到了一个错误“TypeError：无法读取未定义的属性‘map’”

//1.Initial declaration
const App = props=>  {
const [state, changeState]= useState ({
    name:"",
    eventTitle:"",
    details:"",
    objdata:{},
    list:[],
    toggleIndex:"",
    editName: "",
    editEventTitle: "",
    editDetails: "",
    editObj: {}
});


//2.logic comes here


//3.tried using map


{(state.list.map((data,id)=>{
console.log ('loop data',data)
}))}
