How to shuffle an array in JavaScript

Answer 1

const shuffleArray = array => {
    for (let i = array.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
         
        [array[i], array[j]] = [array[j], array[i]];
    }
}
 
const array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 19];
 
shuffleArray(array);
 
console.log(array);
 
 
 
 
/*

[4, 19, 1, 6, 7, 9, 0, 8, 5, 2, 3]
 
*/
