How to Pick Random Element from Array in React Js?

React Js Get Random Item From Array:To get a random item from an array in React.js, you can use the Math.random() method along with array indexing. First, generate a random index using Math.random() multiplied by the array's length. Then, round the result using Math.floor(). Finally, access the array element at that index to obtain a random item.

                const randomIndex = Math.floor(Math.random() * items.length);
                const selectedRandomItem = items[randomIndex];
                setRandomItem(selectedRandomItem);
