如何获取连续元素数组对象的重复键值的计数？

我有一个数组结构：-

 var location = [ {
  "latitude" : 21.112,
  "longitude" : 79.07,
  "time" : "8:13AM",
  "time1" : "8:13AM"
}, 
{
  "latitude" : 21.111,
  "longitude" : 79.07,
  "time" : "8:20AM",
  "time1" : "8:20AM"
}, 
{
  "latitude" : 21.111,
  "longitude" : 79.07,
  "time" : "8:34AM",
  "time1" : "8:34AM"
}, 
{
  "latitude" : 21.111,
  "longitude" : 79.07,
  "time" : "8:41AM",
  "time1" : "8:41AM"
}, 
{
  "latitude" : 21.109,
  "longitude" : 79.07,
  "time" : "8:48AM",
  "time1" : "8:48AM"
}, 
{
  "latitude" : 21.108,
  "longitude" : 79.07,
  "time" : "8:55AM",
  "time1" : "8:55AM"
}, 
{
  "latitude" : 21.108,
  "longitude" : 79.069,
  "time" : "9:02AM",
  "time1" : "9:02AM"
}, 
{
  "latitude" : 21.107,
  "longitude" : 79.069,
  "time" : "9:09AM",
  "time1" : "9:09AM"
}, 
{
  "latitude" : 21.106,
  "longitude" : 79.069,
  "time" : "9:16AM",
  "time1" : "9:16AM"
}, 
{
  "latitude" : 21.105,
  "longitude" : 79.069,
  "time" : "9:23AM",
  "time1" : "9:23AM"
}, 
{
  "latitude" : 21.104,
  "longitude" : 79.069,
  "time" : "9:30AM",
  "time1" : "9:30AM"
}, 
{
  "latitude" : 21.105,
  "longitude" : 79.069,
  "time" : "9:37AM",
  "time1" : "9:37AM"
}, 
{
  "latitude" : 21.105,
  "longitude" : 79.07,
  "time" : "9:44AM",
  "time1" : "9:44AM"
}, 
{
  "latitude" : 21.105,
  "longitude" : 79.071,
  "time" : "9:51AM",
  "time1" : "9:51AM"
}, 
{
  "latitude" : 21.106,
  "longitude" : 79.072,
  "time" : "9:58AM",
  "time1" : "9:58AM"
}]

我要数不行。每个对象的经度和纬度时间相同。它应该仅使用附加的count键返回数组。对于例如-预期结果

var location = [ {
  "latitude" : 21.112,
  "longitude" : 79.07,
  "time" : "8:13AM",
  "time1" : "8:13AM",
  "count":1
}, 
{
  "latitude" : 21.111,
  "longitude" : 79.07,
  "time" : "8:20AM",
  "time1" : "8:20AM",
  "count":3
}, 
{
  "latitude" : 21.111,
  "longitude" : 79.07,
  "time" : "8:34AM",
  "time1" : "8:34AM",
  "count":3
}, 
{
  "latitude" : 21.111,
  "longitude" : 79.07,
  "time" : "8:41AM",
  "time1" : "8:41AM",
  "count":3
},..]

我已经尝试过此代码-

const resultarray = Object.values(location.reduce((a, b) => {
  a[b.latitude + b.longitude] = Object.assign(b, {count: (a[b.latitude + b.longitude] || {count: 0}).count + 1});
  return a;
}, {}));

console.log(resultarray)

但这会返回带有count的元素的唯一对象。我希望每个对象都具有关键计数。
