local storage

As the answers here already talk about the coding aspect. I will talk about
the concept.
Local storage is basically an object stored in the specific browser you are 
using in that moment. And thus it is tied to that browser in that device. It's 
duration is infinite so it never expires

If you only want to store data that only lasts for that browser session(
starts when you open a window and ends when you close it) then the best choice
is sessionStorage

javascript localstorage

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

local storage

localStorage.setItem('localStorage', 1);

local storage

<form action="2.html" onsubmit="callme()">
    <p>Enter your name</p>
    <input id="tbName" type="text">
    <button type="submit" value="submit">Submit</button>
</form>
<script>
    function callme(){
        var name = document.getElementById('tbName').value;
        sessionStorage.setItem('userName', name);
    }
</script>

localstorage in javascript

//localStorage contain key value.
//we can get all localStorage from localStorage tab of storage pannel in inspect.
localStorage.setItem("todo","Feed the cat") //set localStorage with key todo and fee the cat as value
localStorage.clear();// clear the localStorage.
//getting localStorage.
const user = localStorage.getItem('user'); //in parameter we send key value

//adding array and object in localStorage.
//when we use tradition way we get string instead of array and object.
//this issues can be remove by using JSON.stringify and JSON.parse.
const todoList= ["Feed the cat","wash"]
localStorage.setItem("todos",JSON.stringify(todoList)); //changing array to string with []
const retrieved= JSON.parse(localStorage.getItem("todos")); // changing string to object.

local storage

window.localStorage.setItem("grade","One");
//in this case, the `grade` is the key while `One` is the value.

Local Storage

<script>
  //an immediately invoked function that checks to see if the text is in local storage already
  (function(){
    //if the text is in local storage, set the html
    if (localStorage.currentTotal){
    console.log(localStorage.currentTotal);
    document.getElementById('class').innerHTML = localStorage.getItem("currentTotal");
  }
    })();
  //function that gets called for an onclick event
  function myFunction() {
// Store in local storage
localStorage.setItem("currentTotal", "Class current balance total");
//set the inner html to what is in local storage
document.getElementById("class").innerHTML = localStorage.getItem("currentTotal");

}
</script>

local storage

var answer = localStorage.key(1);
// this statement will retrieve the value of the second item in localStorage.
