I have an array that looks like this

    $scope.A = [



          [ "1.31069258855609,103.848649478524", "1.31138534529796,103.848923050526" ],

          [ "1.31213221536436,103.848328363879", "1.31288473199114,103.849575392632" ]



        ];

I want to make it into something like this

        $scope.B = [

           [

             [1.31069258855609,103.848649478524], [1.31138534529796,103.848923050526]

           ],

           [

             [1.31213221536436,103.848328363879], [1.31288473199114,103.849575392632]

           ]

         ];

PS: Sorry if this isnt splitting, I am not sure how to address this problem as

Code:

    var latlngs = $scope.polyLineCord.map(subarr => subarr.map(str => str.split(',').map(Number)))

    console.log(latlngs)

map each item in the outer array, then .map each subarray and split by commas, and map again by Number to transform the strings to numbers:

const input = [

  ["1.31069258855609,103.848649478524", "1.31138534529796,103.848923050526"],

  ["1.31213221536436,103.848328363879", "1.31288473199114,103.849575392632"]

];

console.log(

  input.map(

    subarr => subarr.map(

      str => str.split(',').map(Number)

    )

  )

);

A function to do the job:

function splitMyArray(arr) {

    for (var i = 0; i < arr.length; ++i) {

        var line = arr[i];

        for (var k = 0; k < line.length; ++k) {

            var parts = line[k].split(',');

            line[k] = [parseFloat(parts[0]), parseFloat(parts[1])];

        }

    }

    return arr;

}

Usage example:

var myArr = [

    ["1.31,103.84", "1.32,103.85"],

    ["1.39,103.77", "1.40,103.78"]

];



var splitted = splitMyArray(myArr);

console.log(splitted);
