Do you know that the sort method does not work so well on integers in an array since it is used for strings! 
That is something I found out today so then how to use a sort method on an array that has integers? Simply add a 
custom function to a sort method as an argument like below!
var arr = [1,100,4,30,5,80]
var compare = function(num1,num2){
    if (num1 < num2){
        return -1;
    }
    else if (num1 > num2){
        return 1;
