Randomize an Array

randomizeArray.js

const randomInt = max => (Math.random() * max) | 0;
const randomSort = (array, passes=3)=>{
  for( /*We don't need to declare a new variable*/ ; passes>0; passes--){
    const index1 = randomInt(array.length),
          index2 = randomInt(array.length);
    const temp = array[index1];
    array[index1] = array[index2];
    array[index2] = temp;
  }
}

//Example
const cards = Array(52).fill(0).map((_,index)=>index+1);
console.log("Sorted Pile:");
console.log(cards);
randomSort(cards,1000);
console.log("Shuffled Pile:");
console.log(cards);
