This works var game = ["Rock", "Paper", "Scissors"]; function randomizer() { var random = game[Math.floor(Math.random() * game.length)]; return random; } var rock = game[0]; var paper = game[1]; var scissors = game[2]; function rockfunc() { var random = randomizer(); if(random == rock) { alert("computer chose rock its a draw"); } else if(random == paper) { alert("computer chose paper you lost"); }else{ alert("computer chose scissors you won"); } }

Another version, replaced nested if/else by switch/case and cleaned up a little: var game = ["Rock", "Paper", "Scissors"]; var rock = game[0]; var paper = game[1]; var scissors = game[2]; var random; function randomizer() { random = game[Math.floor(Math.random() * game.length)]; return random; } function rockfunc() { randomizer(); switch(random) { case rock: alert("computer chose rock its a draw"); break; case paper: alert("computer chose paper you lost"); break; case scissors: alert("computer chose scissors you won"); break; } }

@The Coding Sloth Why a default case for the switch? There are only 3 possible cases here, so in this context you don't really need a default case.

if you use a switch statement I would suggest a default at the end

I think switch and break condition would be the best here

Well I used your method first The Coding Sloth and it worked, and then I realized it was just a single line of code I had forgot to write that is "var random = randomizer ();
