如何修改数组对象的值并在 Javascript 上一次比较它？

Question

I am printing on my map locations provide me by API. In some cases locations return the same lat and lng , if for example I get 5 locations and 3 locations have the same locations i only see 3 ubications, because 3 locations is in the same point.

My quickly solution i think is : loop my object array and add 0.00001 or 0.0002 to look all locations on my map .

let points=
[{
        "id": 1,
        "description": "LOC 1",
        "latitude": 37.3676908,
        "longitude": -6.0432685
    },
    {
        "id": 2,
        "description": "LOC 2",
        "latitude": 37.3676908,
        "longitude": -6.0432685
    },
    {
        "id": 3,
        "description": "LOC 3",
        "latitude": 37.3676908,
        "longitude": -6.0432685
    },
    {
        "id": 5,
        "description": "LOC 4",
        "latitude": 37.363128,
        "longitude": -6.0455416
    },
    {
        "id": 6,
        "description": "LOC 5",
        "latitude": 37.369319,
        "longitude": -6.0421527
    }
]

I want to get the next :

let points=
[{
        "id": 1,
        "description": "LOC 1",
        "latitude": 37.3676908,
        "longitude": -6.0432685
    },
    {
        "id": 2,
        "description": "LOC 2",
        "latitude": 37.3676909,
        "longitude": -6.0432686
    },
    {
        "id": 3,
        "description": "LOC 3",
        "latitude": 37.3676910,
        "longitude": -6.0432687
    },
    {
        "id": 5,
        "description": "LOC 4",
        "latitude": 37.363128,
        "longitude": -6.0455416
    },
    {
        "id": 6,
        "description": "LOC 5",
        "latitude": 37.369319,
        "longitude": -6.0421527
    }
]

I've tried to achieve that with .sort and .filter but I dont find nice solution to it.

Could someone help me . Thank you in advance

I think you want map if you want to do an operation to every object in an array.

points.map(x => x + Math.random()/1000) would add a random tiny number.

But you can do whatever function you want on x after the x => part. Maybe something like

points.map(myfunc) and you can define myfunc as add .0001 or add .0002 based on some condition.
