We suppose to do something like this:

var hacker2 = prompt("What's navigator's name?");
console.log("The navigator's name is " + hacker2 + ".");

console.log("The navigator's name is " + hacker2);

//Conditionals
//Measures length of names, outputs string based on who is longer.
if (hacker1.length > hacker2.length) {
console.log("The driver has the longest name, it has " + hacker1.length + " characters");
} else if (hacker2.length > hacker1.length) {
console.log("The navigator has the longest name, it has " + hacker2.length + " characters");
} else {
console.log("Wow, you both have equally long names, " + hacker1.length + " characters!")
}

//Splits driver string into capital letters separated by spaces.
var capSpace = ""

Great!

var lexico = hacker1.localeCompare(hacker2)
if (lexico === -1)
{
console.log("The driver's name goes first");
} else if (lexico === 1) {
console.log("Yo, the navigator goes first definitely.");
} else if (lexico === 0) {
console.log("What?! You both got the same name?");
} else {
console.log("Something bad happened with lexico!");
