React Js use Refs to change image src
React Js use Refs to change image src:In Reactjs, you can use "refs" to dynamically change an image's source (src) attribute. Refs provide direct access to a DOM element or React component. First, create a ref using the
React.createRef() method. Attach this ref to your image element. Then, in your code, you can use the ref to modify the image's src attribute, allowing you to update the displayed image dynamically. This is particularly useful for scenarios like image galleries or when you need to change an image based on user interactions without re-rendering the entire component. Refs offer a way to interact with the DOM imperatively within a React application.

How can React.js refs be used to dynamically change the src attribute of an image element?
In this Reactjs code snippet, a functional component named "App" is created. It utilizes the "useRef" hook to create a reference called "imageRef" to an image element. When the "Change Image" button is clicked, the "changeImage" function is invoked. This function checks if the "imageRef" is defined and, if so, changes the image source to a new URL. This technique allows for dynamic manipulation of the image source without re-rendering the component
