Build a Quiz! 🎯

Let us build a tiny quiz checker! 🧠

It will check if an answer is right using booleans. ✅

The Secret Answer 🤫

First, we save the correct answer in a box. 📦

let correct = "blue";
console.log("Answer saved!");

The Player Guesses 🙋

Now the player picks an answer. We save it too! ✍️

let correct = "blue";
let guess = "blue";
console.log("Guess: " + guess);

Check It! 🔍

We use === to see if the guess matches the correct answer! 🟰

let correct = "blue";
let guess = "blue";
console.log(guess === correct);

Right or Wrong? 🤔

If they match, we get true (correct!). If not, false (try again!). 🎉

A Wrong Guess 😅

Watch what happens when the guess is wrong. 🟢

let correct = "blue";
let guess = "red";
console.log(guess === correct);

Make a Checker Spell 🪄

Remember functions? Let us put our checker in a spell! ✨

function check(guess) {
  return guess === "blue";
}
console.log(check("blue"));

Test Many Guesses 🎲

Now we can test lots of guesses with our spell! 🎉

function check(guess) {
  return guess === "blue";
}
console.log(check("green"));
console.log(check("blue"));

Add a Friendly Message 💬

Let us make it say nice words depending on the answer! 😊

function check(guess) {
  if (guess === "blue") {
    return "Correct! Great job!";
  }
  return "Oops, try again!";
}
console.log(check("blue"));

You Built a Quiz! 🏗️

You used booleans, comparisons, AND a function together! 🤝

That is real coding magic. 🧙

So Many Tools! 🧰

See how everything works together? Booleans, questions, and spells make games! 🎮

You are doing amazing! 🌟
