IT JAVASCRIPT - Please help!

Can someone please help me fix the below code. I need to somehow incorporate JSON to keep track of the score between the computer and the player. Can anyone please help and show me how to do that? Also, the below code shows "undefined" if someones enter "ROCK", "PAPER", "SCISSORS" in all caps? Also is there a way to check if the user enters something other than rock, paper or scissors to re-prompt the question? Please advise. Thank you. Also is there a better way to randomize the computer's choice? I don't quite get what the below code in bold is doing. // Computer choice var input2 = Math.random(); if (input2 < 0.34) { input2 = "rock"; } else if(input2 <= 0.67) { input2 = "paper"; } else { input2 = "scissors"; }
