How to store an array in localstorage

Question

If I don't use localStorage:

var employees=new Array(); 

employees[0]=prompt("New member name?");

This works. However, when I store the variable in localStorage it is not working, the codes I have tried are:

var localStorage[employees] = new Array();
localStorage.employees[0] = prompt("New member name?");

Where am I going wrong?

Localstorage only supports Strings. So you can use JSON.stringify() as the data which is sent to/from a server is JSON, you can convert it into a string with the help of JSON.stringify().

var employees = [];

employees[0] = prompt("New name?");
localStorage.setItem("employees", JSON.stringify(employees));
var storedNames = JSON.parse(localStorage.getItem("employees"));
