• shuffling multiple arrays javascript [duplicate] 2 answers

i want randomly shuffle these 2 arrays in same function

var array1 = [1,2,3,4,5]; var array2 = [6,7,8,9,10]; 

so returns each array randomly shuffled such as

4,2,3,5,1 7,9,6,8,10 

also on return want line break between two, please help?

added shuffle method array.prototype easy access - returns modified array keeping original unchanged.

array.prototype.shuffle = function() {    var rindex, temp,      input = this.slice(0),      cnt = this.length;      while (cnt) {      rindex = math.floor(math.random() * cnt);      temp = input[cnt - 1];      input[cnt - 1] = input[rindex];      input[rindex] = temp;      cnt--;    }      return input;  }    var array1 = [1, 2, 3, 4, 5];  var array2 = [6, 7, 8, 9, 10];    document.getelementbyid('shuffle-btn').onclick = function(){    document.getelementbyid('output').innerhtml = [array1.shuffle(), array2.shuffle()].join('\n');  }

<button id="shuffle-btn">shuffle</button>  <pre id="output"></pre>
