7. What if choice is paper?


#1

I don't know where's the mistake. SyntaxError: Unexpected token else

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";
}
}
};

@coreplayer86446,
For the Javascript interpreter the semi-colon-; is an End-of-Statement indicator.
So do not use them on your IF ELSE-IF IF ELSE statement structure.....

The curly-brackets-{ } are used to encapsulate so-called code-blocks....

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 )
