HTML5 Web Storage

The HTML5 Web Storage feature allows web applications to store data locally in the user’s browser. It provides two mechanisms for storing data: session storage and local storage.

Session storage is a storage mechanism that is available for the duration of a single-page session. It is deleted when the user closes the browser window or tab.

Local storage is a storage mechanism that persists even after the browser window or tab is closed.

Both session storage and local storage provide a simple key-value storage mechanism, similar to cookies. However, they are more efficient and have larger storage limits than cookies.

To use Web Storage in your web application, you can use the sessionStorage and localStorage objects in JavaScript. These objects provide methods for storing, retrieving, and deleting data.

Here is an example of how to store and retrieve data using Web Storage:

// Store data
localStorage.setItem("key", "value");

// Retrieve data
const value = localStorage.getItem("key");

You can also use the removeItem() method to delete data from storage:

localStorage.removeItem("key");

You can learn more about the HTML5 Web Storage feature and how to use it in your web development projects by consulting the documentation on the W3C website or by searching online for tutorials and resources.
