How do I save JavaScript variables permenantly/persistently?

I have 5 arrays, which can all be updated by the user. They are structured as:

var nameStore = [
{ name: "Tim Jones", idn: "i0001" },
{ name: "Mark Gooderham", idn: "i0002" }
];

var nameStoreName;

var subjectStore = [
    { name: "Sailing", ids: "s0001" },
    { name: "Navigation", ids: "s0002" }
];

var subjectStoreName;

var classStore = [
    { name: "Class A", idc: "c0001" },
    { name: "Class 2", idc: "c0002" }
];

var classStoreName;

var roomStore = [
    { name: "Room 1", idr: "r0001" },
    { name: "Room 2", idr: "r0002" }
];

var weekStore = [
    { week: 1, weekTimes: ["mon01i0001s0001c0001r0001", "mon02i0001s0002c0002r0002"] },
    { week: 2, weekTimes: ["mon02i0002s0002c0002r0002"] },
];

I want to be able to store these arrays permanently, so when the webpage closes, the arrays will have their data saved, and can then be accessed by another user later. I know this is a big question, but even if you could just direct me to other resources, that would help.

Thanks.

For that purpose, you should store your arrays in a database. Before closing page, submit arrays to DB and update records. When user opens the webpage, query DB and get arrays' contents.

You can use localStorage to store the array on the browser if you're not using database to persist.

localStorage.setItem('key', JSON.stringify(arr));

var item = JSON.parse(localStorage.getItem('key'));
