What is the best way to manage classNames dynamically in React with Material-UI?

I am wondering how to dynamically add and remove classes from an img tag. My goal is to change the image automatically every 2 seconds, similar to Instagram's signup page. I am struggling to achieve this using the material-ui approach. Below is a snippet of my code where I want to periodically add and remove certain classes.

<div className={classes.phoneImageWrapper}>
  <img src={Phone1} alt="instagram" className={classes.phoneImage} />
  <img src={Phone2} alt="instagram" className={classes.phoneImage} />
  <img src={Phone3} alt="instagram" className={classes.phoneImage} />
  <img src={Phone4} alt="instagram" className={classes.phoneImage} />
  <img src={Phone5} alt="instagram" className={classes.phoneImage} />
</div>

Additionally, here are the styles I intend to toggle between adding and removing phoneImageAnimation and phoneImageVisible classes to the img tag every 2 seconds:

phoneImageWrapper: {
  margin: "10px 0 0 151px",
  position: "relative",
},
phoneImage: {
  top: 100,
  left: 0,
  position: "absolute",
  width: 240,
  height: 427,
  opacity: 0,
  visibility: "hidden",
},
phoneImageAnimation: {
  transition: "opacity 1.5s ease-in",
  zIndex: 2,
},
phoneImageVisible: {
  opacity: 1,
  visibility: "visible",
}

If you want to incorporate a timing function in your React component, you can utilize the setInterval method within the useEffect hook as shown below.

 const [activeIndex, setActiveIndex] = useState(0);

 const images = [
   <img src="/1.webp" alt="1" />,
   <img src="/2.png" alt="2" />,
   <img src="/3.webp" alt="3" />
 ];

  useEffect(() => {
    let timer = setInterval(() => {
      setActiveIndex((prevIndex) => {
        return (prevIndex + 1) % images.length;
      });
    }, 2000);

    return () => {
      clearInterval(timer);
    };
  }, []);

To add animation effects, you can make use of the react-transition-group library.

Utilize the clsx library, a convenient tool designed for this specific purpose.

Set up a variable called image to cycle through each image (based on index or name) every 2 seconds.

<div className={styles.imageContainer}>
  <img src={Image1} alt="example" 
       className={clsx(styles.image, image===0 && styles.visible )} />
  <img src={Image2} alt="example" 
       className={clsx(styles.image, image===1 && styles.visible )} />
  <img src={Image3} alt="example" 
       className={clsx(styles.image, image===2 && styles.visible )} />
  <img src={Image4} alt="example" 
       className={clsx(styles.image, image===3 && styles.visible )} />
  <img src={Image5} alt="example" 
       className={clsx(styles.image, image===4 && styles.visible )} />
</div>

To dynamically change the state of a class, you can utilize the combination of setInterval and useState.

For example, if you have an array of different classes that you wish to rotate through every 2 seconds:

const classes = ['class1', 'class2', 'class3'];

You would also need a state variable to keep track of the current class index:

const [currentIndex, setCurrentIndex] = useState(0);

In a useEffect hook, you can set up an interval to update the index state:

useEffect(() => {
    setInterval(() => setCurrentIndex((currentIndex + 1) % classes.length), 2000);
});

Finally, apply the current class from the array using the className attribute:

<div className={classes[currentIndex]}></div>

And there you have it - a simple way to cycle through different classes dynamically!
