How to save coordinates to an array in a separate file?

Question

JavaScript

Hello, in the application I enter an address and in return I get the coordinates and the name of the autonomous region.
I get 3 lines in the output

results[0].formatted_address.value
results[0].address_components[2].long_name.value
results[0].geometry.location.value

I need to save them to an array in the main.js file, the
array looks like

var Points = [
    {
        object: "ул.Стромынка, д.7",
        district:   "Центральный автономный округ",
        point: [56.0091086,92.8714365]
    },

]

How to write this data to an array so that it persists even after the page is reloaded?

Answer 1

var Points = [ /* коллекция точек */ ];

function save(points) {
  localStorage.setItem('points', JSON.stringify(points));
}

function load() {
  var points = localStorage.getItem('points');
  
  return points ? JSON.parse(points) : [];
}

Answer 2

The data needed after the page is reloaded must be stored somewhere.
And JS is a client-side language, so you can save data using it in several ways some identifier?)
2. In a cookie, but then the data will be available only on the current computer, in the current browser (+ as much time as you specify)
3. In localStorage - the storage method is identical to cookies, the time is unlimited.
