“(51.60693037835707, -99.25735473632812),(45.816357959181346, -93.19290161132812),(45.13846137581871, -121.93313598632812),(51.60693037835707, -99.25735473632812),…..”

to

{

1:{“lat”:51.60693037835707,”lan”:99.25735473632812},

2:{“lat”:45.816357959181346,”lan”:93.19290161132812},

3:{“lat”:45.13846137581871,”lan”:121.93313598632812},

.

.

.

}

then here is the simple code

var string=”(51.60693037835707, -99.25735473632812),(45.816357959181346, -93.19290161132812),(45.13846137581871, -121.93313598632812),(51.60693037835707, -99.25735473632812).”

 

var array=string.split(“,”);
var coordinates_array=[];
array.forEach(function(value,key){
var obj={};
if(key & 1){
var first=array[key].replace(‘)’,”);
coordinates_array.push(first)
}else{

var sec=array[key].replace(‘(‘,”);
coordinates_array.push(sec)

}
})
// console.log(coordinates_array);changing the string to array excluding ‘(‘ &  ‘)’
var i=-1;
var obj={};
var result={};
coordinates_array.forEach(function(value,key){
if(key %2 ==0){
i++;
result[i.toString()]={};
delete obj;
}
if(key & 1){
result[i.toString()][“lan”]=value
}else{
result[i.toString()][“lat”]=value

}

})

console.log(result)// desire result
