How to randomize a javascript array?

Hello guys I know how to generate a random value with Math.random() in Javascript, but can you tell me how to mix numbers randomly?

For example I have numbers 1,2,3,4,5,6,7,8,9,10 how to mix it randmoly like this: 2,8,9,1… so each number should be used only once

Answer 1

You could do this by putting them all in an array and sort that array in a random fashion.

var nrs = [1,2,3,4,5,6,7,8,9,10];
nrs.sort(function(a,b){
    return Math.floor(Math.random()*3 - 1);
});
