My solution to the Random Number Challenge!

// Collect input from a user let userAge = prompt("How old are you?");

// Convert the input to a number userAge = parseInt(userAge); console.log(typeof userAge, userAge);

// Use Math.random() and the user's number to generate a random number let alienYears = Math.floor(Math.random() * userAge); console.log(alienYears);

// Create a message displaying the random number document.querySelector("main").innerHTML = <h1>Woah, you're ${alienYears} years old in Alien Years!;

Thanks for your help, my mistake was that I put the users input number inside the Math.random() instead of multiplying it.
