how to randomize order of an array code example
Example 1: how to shuffle an array javascript
function shuffle(a) {
var j, x, i;
for (i = a.length - 1; i > 0; i--) {
j = round(random() * (i + 1));
x = a[i];
a[i] = a[j];
a[j] = x;
}
return a;
}
shuffle(array);
Example 2: how to randomize an array
const getShuffledArr = arr => {
const newArr = arr.slice()
for (let i = newArr.length - 1; i > 0; i--) {
const rand = Math.floor(Math.random() * (i + 1));
[newArr[i], newArr[rand]] = [newArr[rand], newArr[i]];
}
return newArr
};
