My solution (that seems to be working)

As I've never posted here, I thought this would be a great chance to open my post score here on Teamtreehouse.

I think it's so crazy that just around a week ago, I hadn't written a single line of code and now I did this.

Thank you Teamtreehouse!

// First question
let score = 0;
let firstQuestion = prompt("What is the capital of Estonia?").toLowerCase();
if (firstQuestion === "tallinn") {
    score += 1;
    alert("Correct!");
} else {
    score -= 0;
    alert("Wrong!");
}
console.log(firstQuestion + ": Score so far: " + score);

// Second question

let secondQuestion = prompt("What is the capital of Hungary?").toLocaleLowerCase();
if (secondQuestion === "budapest") {
    score += 1;
    alert("Awesome! That's correct!");
} else {
    score -= 0
    alert("That is not correct!");
}
console.log(secondQuestion + ": Score so far: " + score);

// Third question

let thirdQuestion = prompt("What is the capital of Finland?").toLocaleLowerCase();
if (thirdQuestion === "helsinki") {
    score += 1;
    alert("That's correct!");
} else {
    score -= 0;
    alert("That is not correct!");
}
console.log(thirdQuestion + ": Score so far: " + score);

// Fourth question

let fourthQuestion = prompt("What is the capital of Australia?").toLocaleLowerCase();
if (fourthQuestion === "canberra") {
    score += 1;
    alert("That's correct!");
} else {
    score -= 0;
    alert("That is not correct!");
}
console.log(fourthQuestion + ": Score so far: " + score);

// Fifth question

let fifthQuestion = prompt("What is the capital of Bulgaria?").toLocaleLowerCase();
if (fifthQuestion === "sofia") {
    score += 1;
    alert("That's correct!");
} else {
    score -= 0;
    alert("That is not correct!");
    alert("That is the end of the quiz. Thank you!");
}
console.log(fifthQuestion + ": Score so far: " + score);



let prize = "";


if (score === 5) {
    prize = "gold";
} else if (score < 5 && score > 3) {
    prize = "silver";
} else if (score <= 3 && score > 0) {
    prize = "bronze";
} else {
    prize = "nothing";
}
console.log(prize);
alert("You got " + prize);

Good job, and great start on coding! :+1:

One little suggestion: when you have an "if ... else if" chain, you don't need to re-test conditions that would be caught by previous tests, so you can simplify it a bit:

if (score === 5) {
    prize = "gold";
} else if (score > 3) {
    prize = "silver";
} else if (score > 0) {
    prize = "bronze";
// ...

But that's very minor compared to the consolidation you'll be able to achieve when you get to functions.

You're right, it makes more sense. Thank you for the tip!
