Solution 1:
For example: To generate 8 unique random numbers and store them to an array, you can simply do this:
var arr = [];
while(arr.length < 8){
var r = Math.floor(Math.random() * 100) + 1;
if(arr.indexOf(r) === -1) arr.push(r);
}
console.log(arr);Solution 2:
- Populate an array with the numbers 1 through 100.
- Shuffle it.
- Take the first 8 elements of the resulting array.
