javascript - 查找两个单独的 JavaScript 对象之间的重复值？

Question

我有两个 javascript 对象数组:

var fullDateRange=[{date:"4/1/18",value:0},{date:"4/2/18",value:0},{date:"4/3/18",value:0},{date:"4/4/18",value:0},{date:"4/5/18",value:0}]

和

var actualDateRange=[{date:"4/1/18",value:1},{date:"4/3/18",value:3},{date:"4/5/18",value:5}]

我正在尝试循环访问 fullDateRange 数组，查看是否存在任何实际的DateRange 日期，然后递增该值。但我不断收到重复的代码:

   function outputDeltaDates(fullDateObj, responseObj) {
    var dateArr = [],
      valueArr = [];
    $.each(fullDateObj, function(index) {
      var fullDate = this;
      var counter = 0
      $.each(responseObj, function(index) {
        var fullResponse = this;
        if (fullResponse['date'] == fullDate['date']) {
          valueArr.push(fullResponse['value'])
          dateArr.push(fullDate['date'])
        } else {
          if (!dateArr.includes(fullDate['date'])) {
            valueArr.push(0)
            dateArr.push(fullDate['date'])
          }
        }
      })
    })
    return [valueArr, dateArr]
  }

如果日期存在于另一个数组中，则要增加对象值属性，只需循环一次，如果在 actualDateRange 中找到日期，则增加值

var fullDateRange=[{date:"4/1/18",value:0},{date:"4/2/18",value:0},{date:"4/3/18",value:0},{date:"4/4/18",value:0},{date:"4/5/18",value:0}]
var actualDateRange=[{date:"4/1/18",value:1},{date:"4/3/18",value:3},{date:"4/5/18",value:5}]

fullDateRange.forEach(e => {
    let act = actualDateRange.find(a => a.date === e.date);
    if (act) e.value += act.value;
})

console.log(fullDateRange);
