React Js Session Storage Example
React Js Session Storage Example:ReactJS is a JavaScript library for building user interfaces. Session Storage is a web browser feature that allows storing key-value pairs temporarily. In React, you can use the sessionStorage object to store data that persists within the same browser session. This can be helpful for managing state or user preferences without using server-side storage. React components can access and modify session storage using methods like sessionStorage.setItem() and sessionStorage.getItem(). Remember, session storage data is limited to the current tab and is cleared when the tab is closed. Utilizing React with session storage enhances client-side data management.

How can React JS utilize session storage for managing state or data within a user's session?
The provided code snippet demonstrates the usage of ReactJS to create a simple user login interface that utilizes the browser's session storage. It begins by importing the useState hook from React and setting up a functional component called App. Inside this component, a user's name is collected through an input field.
When the "Login" button is clicked, the user's name is stored in the session storage using sessionStorage.setItem(). If a name is stored, a personalized welcome message is displayed; otherwise, a prompt to log in is shown. The UI is rendered using ReactDOM. This technique is useful for temporary data storage during a user's session on a website.
