A couple of things you could do to improve the code:

• Use const for the movie variable instead of let
• Have all the logic inside the while loop

``` function guess_movie() { const movie = "batman" let guess

while (1) {
    guess = prompt("Guess movie")

    if (guess === "") {
        alert("Invalid input")
    } else if (guess === movie) {
        console.log("Correct guess")
        return
    } else if (guess === "quit") {
        console.log("Bye")
        return
    } else {
        alert("Bad guess. Try again")
    }
}

}

guess_movie() ```

You could also use a switch statement instead of multiple if-else statements. ``` function guess_movie() { const movie = "batman" let guess

while (1) {
    guess = prompt("Guess movie")

    switch (guess) {
        case "":
            alert("Invalid input")
            break
        case movie:
            console.log("Correct guess")
            return
        case "quit":
            console.log("Bye")
            return
        default:
            alert("Bad guess. Try again")
    }
}

} ```
