Using local storage with javascript code example

Example 1: local storage javascript

function createItem() {
	localStorage.setItem('nameOfItem', 'value'); 
} 
createItem() // Creates a item named 'nameOfItem' and stores a value of 'value'

function getValue() {
	return localStorage.getItem('nameOfItem');  
} // Gets the value of 'nameOfItem' and returns it
console.log(getValue()); //'value';

Example 2: localstorage javascript

localStorage.setItem(key, val);
var val = localStorage.getItem(key);
localStorage.removeItem(key);
localStorage.clear();

Example 3: 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 4: javascript localstorage

var KeyName = window.localStorage.key(index);
