Would this also be correct?

// Collect input from a user const userNum1 = prompt ("Please enter a low number."); const userNum2 = prompt ("Please enter a high number")

// Convert the input to a number const lowNum = parseInt(userNum1); const highNum = parseInt(userNum2);

if (userNum1 && userNum2) {

// Use Math.random() and the user's number to generate a random number const randomNum = Math.floor(Math.random(userNum1) * userNum2) + 1;

// Create a message displaying the random number

alert(This is you random number ${randomNum})

} else { alert("You need to provide a number please try again.")

}

Combining numbers using logic operators (such as if (userNum1 && userNum2)) is not a reliable way to test for valid numbers. For example, if either number were 0, the test would fail even though 0 is a valid number.

Also, the random function does not take an argument, so passing it the first number doesn't do anything. More importantly, it won't impose any limit on the lowest possible number chosen like the conventional formula will.
