setting items to localStorage 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: javascript storage get set item

// *** JS Storage Get/Set item *** 

	let target = document.getElementById("target");
    let increment = document.getElementById("increment");
    let count = localStorage.getItem("counter") || 0;
    target.innerHTML = count;

    increment.addEventListener("click", () => {
        count++;
        localStorage.setItem("counter", count);
        target.innerHTML = count;
    })
