// use Math.round() will give an uneven distribution!
function getRandomInt(min, max)
{
 return Math.floor(Math.random() * (max - min + 1)) + min;
}

Where is the guarantee that there will be repeats ? - nikita.Stracke commented on July 8th 19 at 16:06

: use an array where to put the resulting value and look for in this match. If there is, then generate a new number - Violet_Wiso commented on July 8th 19 at 16:09

Solution

var arr = [];
while (arr.length < 10) {
 var n = Math.floor(Math.random() * 30) + 1;
 if (arr.indexOf(n) == -1) {
arr.push(n);
}
}

always "10" returns( - nikita.Stracke commented on July 8th 19 at 16:04

: see the array arr, there will be values with arr.shift them out. - Violet_Wiso commented on July 8th 19 at 16:07
