Array to separate object – Twitter API

I want to convert below array to mentioned separate objects. These are polygon coordinates from twitter. I am getting the tweet locations and want to store somewhere in a separate object. But this array is coming from Twitter API is little different.

    You can use Array.reduce()

    var arr = [
    [76.70535130773267, 30.70314577305184],
    [76.70535130773267, 30.70314577305184],
    [76.70535130773267, 30.70314577305184],
    [76.70535130773267, 30.70314577305184]
];

var result = arr.reduce((a,curr)=>{
  a.push({
    "lat" : curr[1],
    "lng" : curr[0]
  });
  return a;
},[]);

console.log(result);

    Use Array.map

    let arr = [[[76.70535130773267, 30.70314577305184],[76.70535130773267, 30.70314577305184],[76.70535130773267, 30.70314577305184],[76.70535130773267, 30.70314577305184]],[[76.515454, 30.569094],[76.860158, 30.569094],[76.860158, 30.938966],[76.515454, 30.938966]]];
let result = arr.map(a => a.map(([lng, lat]) => ({lat, lng})));
console.log(result);

    You can use map to convert the array of arrays into an array of objects.

    var arr = [
  [76.70535130773267, 30.70314577305184],
  [76.70535130773267, 30.70314577305184],
  [76.70535130773267, 30.70314577305184],
  [76.70535130773267, 30.70314577305184]
]

var result = arr.map(([lat, lng]) => ({lat,lng}))

console.log(result);
