Lesson 7


#1



Not quite sure what I'm doing wrong: I keep getting a syntax error pertaining to the "else" keyword, which I'm not sure where that is. Can someone help me?


var compare = function(choice1, choice2) {
    if (choice1 === choice2) {
        return "The result is a tie!";
    }
    else if (choice1 === "rock") {
        if (choice2 === "scissors") {
            return "rock wins";
        }
        else
        {
            return "paper wins";
        }
        else if (choice1 === "paper") {
            if (choice2 === "rock") {
                return "paper wins";
            } 
            else 
            {
                return "scissors wins";
            }
    }
        
}

@neronia,
You are not using a closing-curly-bracket-} to close the ELSE-IF

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

Please read

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 )
