Randomize elements in a JavaScript array

We randomize elements in a JavaScript array using various approaches. Here, I have used Fisher-Yates Sorting Algorithm in this swap each element in the array with the randomly selected element from the remaining un-shuffled portion of the array.

function shuffleArr(arr) {
    for (let i = arr.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [arr[i], arr[j]] = [arr[j], arr[i]];
    }
    return arr;
}

const originalArr = [11, 22, 33, 44, 55];

const shuffledArr = shuffleArr(originalArr);

console.log(shuffledArr);
