如果他们是同一家餐厅,我想将同一家餐厅在同一个对象下的不同违规行为与新的违规密钥结合起来。就像下面的代码

这是我写的函数
const consolidate = (dataArray) => {
let a = 0;
let nxt = 1;
let holdingArray = [];
while ( nxt < dataArray.length-1 ) {
let newObj;
// if same restaurant
if ( dataArray[a].camis === dataArray[nxt].camis ) {
// when this is the first iteration of restaruant
newObj = nxt - a === 1
? {

}]
};
console.log(newObj) <<<<<<<<<<
nxt ++;
} else {
holdingArray.push(newObj);
a = nxt;
nxt = nxt + 1;
};
};
return holdingArray;
};
const consolidation=(数据数组)=>{
设a=0;
设nxt=1;
设holdingaray=[];
while(nxt console.log(newObj)错误消息中指出了故障线路。您正在尝试在newObj
上访问inspection
为了更好地理解,我在下面的代码中复制了您的错误:
let newObj;
newObj={
检查:newObj.inspection//newObj此时仍未定义
}
我想我应该尝试一下您的逻辑,使用reduce
。它为每个对象设置一个冲突
数组,以确保一致性,并大大减少代码库。如果您在冲突数组之外细化对象,那么也很容易添加到这个数组中

您应该以文本而不是图像的形式发布错误,以提高网站搜索引擎的可读性和索引,谢谢您的提示!我以后一定会这样做。
