@krishna.sudhan,
You will have to change your

else if (choice1 === "paper") {
    
    if (choice2 === "rock")
    
    return "paper wins";
    
}
}
else {
    
    return "scissors wins";
}
}

into

else if (choice1 === "paper") {
    
    if (choice2 === "rock")
        return "paper wins";
    }
    else {
        return "scissors wins";
    }
}

computerChoice = "paper";
} else {
computerChoice = "scissors";
} console.log("Computer: " + computerChoice);
var compare = function(choice1,choice2) {

@krishna.sudhan,

Please read
http://www.codecademy.com/forum_questions/559dcb4be39efe550f00006b
and concentrate on:

  • the creation of the compare function
  • the truth-table
  • the build of the IF ELSE-IF statement structure as part of the compare FUNCTION-BODY
  • the execution of the compare function (keeping in mind that the return statement is used )
