JavaScript 3 diferent ways to do random

 1st is the simplest, number is the interval of  to 0 - to 'number', like if want to sort to 10 or to 100 or to 1000, or if you want draw lots just 6 friends:

    function ram (number) {

        return Math.floor(Math.random()*number);

}

2nd we want to draw lots between two limits, for instance of 7 till 25:

        function random(begging, end) {

            let xz1 = Math.floor(Math.random()*(end+1));

            if(xz1<begging){

                while(xz1<begging){

                    return random(begging,end);

                }

            }else {

                return xz1;

            }

           

        }

But have other way, is you create an loop to store all the numbers that will be sort and they gotting a place in a array, so the first number is the 9 but will be in the itemArray[0], and create a function that sort the index and return the number inside the item idexed.
