how to get specific column's data as list from object in javascript?

Issue

suppose we have the following json data

var example = [{
    latitude: 11.1111,
    longitude: 111.111,
    name: "for example1",
    altitude: 88
},
{
    latitude: 22.2222,
    longitude: 222.222,
    name: "for example2",
    altitude: 89
},
{
    latitude: 33.3333,
    longitude: 333.333,
    name: "for example3",
    altitude: 90
}
]

I want to get the lists(or object) that has only latitude and longitude data, because Map API in my
react-native application require them. and by some performance issues, I can't use loop.
I know that writing a separate query(MySQL) can solve this problem, but I don't think this is good solution. (If not, I will very grateful if you can tell me)

thank you for reading this, how can I solve this?

Solution

I think you need this. it returns a new array with only lat/long items in objects

const newArray = example.map(el => {
    return {
        latitude: el.latitude,
        longitude: el.longitude
    }  
})
