Question

all else statements give an unexpected token error

var men = 50;
alert("You are a Spartan warrior about to be fighting in the Trojan War, you get onto             your ship and set sail with a fleet of other ships but your ship breaks away from the others in a horrible storm! You have 50 men on your ship, do not lose more than 40 of them, or else.");
var start = confirm("are you ready to start?");
if (start = true) {
   alert("your platoon of Spartan soldiers is on a ship, headed for Troy");
}
else {
   alert("You failed in your mission and are executed in Sparta the next day (refresh the page)")
};
var hydra  = prompt("you encounter a large hydra on your journey to Troy, do you sail past it, or fight it?(fight or flee?)");
if (hydra = "fight") {
   alert("You kill the Hydra, but it has killed 8 of your men");
};
else {
   alert("You go around the Hydra, but it snatches up 6 of your men and starts to follow your ship!");
};
if (hydra = "fight") {
   men = 42
}
else {
   men = 44; 
};
console.log(men);

Answer 1

First thing (not a syntax error, but wrong anyway): Compare using == instead of = .

Your syntax error is that you're using ; after the if blocks – remove those.

Answer 2

The unexpected token error is because you end the else's with }; but should only be }

Answer 3

replace if (start = true) with if (start == true) instead. And }; but should only be }
