Use JavaScript to Display Random Trivia on Click

Create an array of random trivia facts and use a JavaScript function to display a different fact each time a user clicks a button.

How would you do this with audio files randomly played on click of that button? None of the tutorials or forums I've visited have helped me make this work yet!

Thank you so much! Ive been trying to make a program like this forever and all the other sources i looked up made their code way more complex.

Anyone know how after you show a random array to push or slice it into another array so it doesn't pop up twice? I can't seem to figure it out.

I used your tutorial as the logic for craps program. My question is: Am I on the right track for adding the sum of two random numbers pulled from two different arrays?

//button event will generate 2 random numbers and add them together

var num1 = [1, 2, 3, 4, 5, 6];
var num2 = [1, 2, 3, 4, 5, 6];
//var sum1 = [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
var sum2 = num1 + num2

function rollDice(){
var randomNumber = + num2));
= randomNumber[rollDice];
}

Thanks a million it is very good and easy. But I have a question, I want to have multiple choice questions in my array and I need to use j query instead of "getElementById", what should I do? If you help me with this I will thankful million times. It`s kinda urgent dear Ralph.

Cannot make it work, google says "Uncaught SyntaxError: Unexpected token } index2.html:16" witch is something to do when i call function (onclick) or the JS itself... i have literally copied the text on the video...
EDIT: deleted half bottom of HTML page and redid it in notepad, for some reason there where some ?"invisible characters"? messing the code....
