local storgae add code example

Example 1: how to get data from localstorage in javascript

//localStorage is an object, so values are stored by key name
//data from localStorage is always stored in strings
//usually the values at each key are stringified objects in JSON format, therefore we must parse them
var data = JSON.parse(localStorage.getItem("key name"));//make sure the "key name" exists in the localStorage

Example 2: my local storage

/* function for setIetm to local storage */

function set(){
    var sendJson = JSON.stringify(allwish);
    localStorage.setItem("wishKay",sendJson);
}
