我想要一个通用的javascript函数，它应该接受一个对象数组.每个对象都有一个小时属性，这是一个数组，可以在下面的代码中看到.每个小时显示每天不同的时间.现在我需要过滤时间.如果从周一到周二的时间(从和到)是相同的，那么它应该显示：M-T:9-5PM W-T:9-9PM Sat-Sun:Closed如果从周一到周五的时间是相同的，并且在周六或周日不同，它应该显示M-F:9-5PM Sat:9-9PM and sun:closed。
我应该返回数组中的数据，这样我就可以在UI中以下面的格式显示，它应该返回包含这些数据的数组，这样就可以很容易地在前端使用循环来渲染。
例如：我把两个对象放在一个数组中，总的来说我希望只显示一次不同的时间。
像这样的吗？
const myHours = myData.map(item => {
const aggHours = item.hours.reduce((aggArr, obj) => {
const len = aggArr.length;
const last = len - 1;
//console.log(len, obj, aggArr)
if (len == 0){
aggArr.push({...obj, dayStr: obj.day});
}
else if (aggArr[last].fromHour == obj.fromHour
&& aggArr[last].toHour == obj.toHour) {
aggArr[last].dayStr = aggArr[last].day + " - " + obj.day;
}
else {
aggArr.push({...obj, dayStr: obj.day});
}
return aggArr;
}, []);
return {id: item.id, aggHours: aggHours.map(elem => {
if (elem.closed){
return {day: elem.dayStr, time: 'closed'};
}
else {
return {day: elem.dayStr, time: elem.fromHour + ' - ' + elem.toHour};
}
})};
});
console.log(myHours);<script id="loadData">
