i'm getting uncaught type error of:
Uncaught TypeError: Cannot set property 'onclick' of null



    
        dice app

js code:

var button = document.getElementById("button");


button.onclick = function() {// error
    var print = dice.roll();
    printNumber(print);
};

Answer

You're executing your JavaScript before the elements exist. Either move your code to the end of the page or put it within an onload handler.

Ex:



    
        dice app
