how to create a javascript object without double quotes on the property value

From this data

[{"lat":"-1.325416","lng":"36.669051"},
 {"lat":"-1.392932","l‌​ng":"36.768752"},
 {"l‌​at":"-1.390505","lng‌​":"36.810023"},
 {"lat‌​":"-1.448266","lng":‌​"36.952769"},
 {"lat":‌​"-1.267033","lng":"3‌​7.094882"},
 {"lat":"-‌​1.214605","lng":"37.‌​053978"},
 {"lat":"-1.‌​169516","lng":"36.89‌​5608"}]

I am trying to create a javascript object that looks like this.

 var outerCoords =[
          {lat: -1.325416, lng: 36.669051},
          {lat: -1.392932, lng: 36.768752},
          {lat: -1.390505, lng: 36.810023},
          {lat: -1.448266, lng: 36.952769},
          {lat: -1.267033, lng: 37.094882},
          {lat: -1.214605, lng: 37.053978}, 
          {lat: -1.169516, lng: 36.895608},
          {lat: -1.244058, lng: 36.730391}
        ],

the property value without double quotes. I have first, stringified my json to get a string, then removed the double quotes from the string, then parsed the result with no double quotes. Parsing the result does not create an object, it returns a string. Please if you can help i'll appreciate. This is what am doing.

var str= JSON.stringify(outercords1); 
var x = str.replace (/"/g,'');
var obj= JSON.parse(x);

the value of outercords is:

[{"lat":"-1.325416","lng":"36.669051"},{"lat":"-1.392932","lng":"36.768752"},{"lat":"-1.390505","lng":"36.810023"},{"lat":"-1.448266","lng":"36.952769"},{"lat":"-1.267033","lng":"37.094882"},{"lat":"-1.214605","lng":"37.053978"},{"lat":"-1.169516","lng":"36.895608"}]

You can use JSON.parse with a custom reviver function to manipulate your elements.

var outderCoords1=[{"lat":"-1.325416","lng":"36.669051"},
 {"lat":"-1.392932","lng":"36.768752"}];

var outerCoords = JSON.parse(JSON.stringify(outderCoords1), 
   function(name, value) {
   if(!(typeof value.replace === "undefined")){
       var v= parseFloat(value.replace(/"/g, ""));
            alert(typeof(v));
           } 
        });

Well I think don't use stringify that solve your problem try it as it is.

You could iterating the array and the objects and convert all stringed numbers to number.

The keys have, according to the JSON, always double quotes.

 var outerCoords = [{ "lat": "-1.325416", "lng": "36.669051" }, { "lat": "-1.392932", "lng": "36.768752" }, { "lat": "-1.390505", "lng": "36.810023" }, { "lat": "-1.448266", "lng": "36.952769" }, { "lat": "-1.267033", "lng": "37.094882" }, { "lat": "-1.214605", "lng": "37.053978" }, { "lat": "-1.169516", "lng": "36.895608" }];

outerCoords.forEach(function (o) {
    Object.keys(o).forEach(function (k) {
        if (isFinite(o[k])) {
            o[k] = +o[k];
        }
    });
});

console.log(outerCoords);
.as-console-wrapper { max-height: 100% !important; top: 0; }

    {lat: -1.244058, lng: 36.730391}
]
        
var str= JSON.stringify(outerCoords); 
//var x = str.replace (/"/g,'');
var obj= JSON.parse(str);
console.log(obj);

Stringified JSON has quoted properties. This is mandatory. So a javascript object in the form

var outerCoords =[
      {lat: -1.325416, lng: 36.669051},
      {lat: -1.392932, lng: 36.768752},
      {lat: -1.390505, lng: 36.810023},
      {lat: -1.448266, lng: 36.952769},
      {lat: -1.267033, lng: 37.094882},
      {lat: -1.214605, lng: 37.053978}, 
      {lat: -1.169516, lng: 36.895608},
      {lat: -1.244058, lng: 36.730391}
    ],

Will be stringified as

'[{"lat":-1.325416,"lng":36.669051},{"lat":-1.392932,"lng":36.768752},{"lat":-1.390505,"lng":36.810023},{"lat":-1.448266,"lng":36.952769},{"lat":-1.267033,"lng":37.094882},{"lat":-1.214605,"lng":37.053978},{"lat":-1.169516,"lng":36.895608},{"lat":-1.244058,"lng":36.730391}]'

removing the quotes will turn it invalid to be parsed as JSON, so that's why you're getting a string.

On the other hand, performing

JSON.parse('[{"lat":-1.325416,"lng":36.669051},{"lat":-1.392932,"lng":36.768752},{"lat":-1.390505,"lng":36.810023},{"lat":-1.448266,"lng":36.952769},{"lat":-1.267033,"lng":37.094882},{"lat":-1.214605,"lng":37.053978},{"lat":-1.169516,"lng":36.895608},{"lat":-1.244058,"lng":36.730391}]');

Will give you an object. The same object you hand when you begun.

Object properties are always casted as strings, so declaring your object as

var outerCoords =[
  {"lat": -1.325416, "lng": 36.669051},
  {"lat": -1.392932, "lng": 36.768752},
  {"lat": -1.390505, "lng": 36.810023},
  {"lat": -1.448266, "lng": 36.952769},
  {"lat": -1.267033, "lng": 37.094882},
  {"lat": -1.214605, "lng": 37.053978}, 
  {"lat": -1.169516, "lng": 36.895608},
  {"lat": -1.244058, "lng": 36.730391}
];

is the same as declaring it without quotes.
