发生错误期望执行赋值或函数调用，而是看到了表达式no-unused-expressions

Question

我想通过一个命令在div中显示包括注释（即对象数组）的完整对象，但是注释的map函数出现错误。请帮助我....

 const fields2 = [

    {
        month: 30,
        unitrate: 2,
        budget: 6000,
        comments: [
            {
                id: 4500,

            },
            {

            },
]
}
];


render() {

        return (
            <div>

                { fields2.map((ob,index)=>{ return (ob.month  +" " + ob.comments.map((ok,index)=>{ ok  }   )) }) }
            </div>
        )
    }

Answer 1

您可以使用下面提到的代码

 { fields2.map((ob,index)=>{ return (ob.month  +" " + JSON.stringify(ob.comments,null,4)) }) }
