Difference between local Storage, cookies, session storage?

Question

Accepted Answer

Local Storage, cookies, and session storage are all ways to store data on the client side, but they have different purposes and limitations.

Local Storage: stores data with no expiration date, and it remains after the browser is closed. Can store larger amounts of data compared to cookies. Example: localStorage.setItem('key', 'value')
Cookies: stores data that has an expiration date and is sent to the server with every request. Limited to 4KB of data. Example: document.cookie = 'key=value; expires=Sun, 1 Jan 2023 00:00:00 UTC'
Session Storage: stores data for one session only, and is deleted when the browser tab is closed. Can store larger amounts of data compared to cookies. Example: sessionStorage.setItem('key', 'value')
