My solution for the self-destruct challenge

My solution.

// 1. Display an alert dialog with the content: "Warning! This message will self-destruct in"
alert("Warning! This message will self-destruct in...");

// 2. Display a "3... 2... 1..." countdown using 3 alert dialog boxes
for( let i = 3; i > 0; i--) {
    alert(`${i}...`);
}

// 3. This statement selects the <h1> element and replaces its text with "BOOM!".
document.querySelector("h1").textContent = "🔥BOOM!🔥";

// 4. Log "Message destroyed!" to the console
console.log("Message destroyed!");
