درخواست توضیح کد در React.js

سلام. کد زیر مال من هست:

 constructor(props) {

   super(props);

   this.state = {

     id_1: {

       name: "David Johns",

       date: "12/12/2022",

       comment: "Hi there! I found your app really ugly.",

     },

     id_2: {

       name: "Carry Smith",

       date: "03/11/2022",

       comment: "Hi there! I found your app really pretty.",

     },

     showComment: true,

   };

 }

commentloop = () => {

   const comments = [];

   let keys = Object.keys(this.state);

   for (const id in this.state) {

     if (id !== keys[keys.length - 1]) {

       comments.push(

         <div key={id}>

           <Comment

             name={this.state[id].name}

             date={this.state[id].date}

             comment={this.state[id].comment}

             click={this.changeName.bind(this, 'James Cameron')}

             change={(event) => this.changeValue(event, id)}

           />

           <button onClick={this.changeName.bind(this, 'Hue Jackman')}>Change name</button>

           <AcceptBtn class="App-flex" />

         </div>

       );

     }

   }

   return comments;

 };

و کد زیر رو از ChatGPT برای property تغییر changeValue گرفتم:

changeValue = (event, name) => {

    const { value } = event.target;

    this.setState(prevState => ({

      [name]: {

        ...prevState[name],

        name: value

      }

    }));

  };

کدی که ChatGPT نوشته رو متوجه نمی‌شم. اگه می‌شه توضیح بدین.
