Run code snippetfunction shuffle(array) {
let currentIndex = array.length, randomIndex;
// While there remain elements to shuffle...
while (currentIndex != 0) {
// Pick a remaining element...
randomIndex = Math.floor(Math.random() * currentIndex);
currentIndex--;
// And swap it with the current element.
[array[currentIndex], array[randomIndex]] = [
array[randomIndex], array[currentIndex]];
}
return array;
}
// Used like so
var arr = [2, 11, 37, 42];
shuffle(arr);
console.log(arr);let array = [1, 2, 3, 4, 5];
for(let i = array.length - 1; i >= 1; i--) {
let j = Math.floor(Math.random() * (i + 1)); // 0 <= j <= i
let temp = array[j];
array[j] = array[i];
array[i] = temp;
}
console.log(array);
