react怎么修改属性值

this.setSate({ 
 toList: response.data 
})

this.todoList = response.data;

 state = {//类似于Vue里面的data()
    todoList: [
      {
        img: "xxx",
        name: "小飞",
      },
      {
        img: "xxx",
        name: "小候",
      },
    ]
  };

this.todoList[0].name = "Jony";
//或者
this.$set(this.todoList[0],"name","Jony");

 this.setState({
      todoList[0].name:"Jony"
    })
    //这样报错了，立马想到另一种方式
   let obj = {
      img:"xxx",
      name:"Jony"
    }
    this.setState({
      todoList[0]:obj
    })

//三目运算符 `key == 0` 是我写死的
//如果是点击传入的话可以是`key == index(下标)`
 const todoList = [...this.state.todoList];   //浅拷贝一下
  this.setState({
      todoList: todoList.map((item,key)=>key == 0?{...item,name: "Jony"}:item)
    });
