                        {
                        arr.push(finalresult.routes[0].geometry.coordinates[i])

You can access it by creating a variable outside the ajax and setting its value inside the success function. Also note you can get its value only after the ajax & its success has finished its execution. For this you can use ajax done. Otherwise it is always going to give an empty array

let arr = [];
$.ajax({
  type: "GET",
  url: url,
  success: function(finalresult) {

    for (var i = 0; i < finalresult.routes[0].geometry.coordinates.length; i++) {
      arr.push(finalresult.routes[0].geometry.coordinates[i])
      global_data = arr.push

    }
  }
}).done(function() {
  console.log(arr)
});
