To achieve this you'll often use Math.random() & Math.floor() functions. An exemples:

var nbr1 = Math.floor((Math.random() * 10) + 1); //Return a random number between 1 and 10:
var nrb2 =  Math.floor((Math.random() * 100) + 1); // Return a random number between 1 and 100;

Hope this helps.

here's how I did it:

var userNum = prompt("Enter a number");
var rando = (Math.random() * parseInt(userNum)) + 1;
rando = Math.floor(rando);
alert(rando);
