The Conditional Challenge Solution

I want to ask if its also good way to output rank like that instead of like its showing in solution video?

if (score === 3 || score === 4 || score === 5) {
  document.write("You got golden crown!!! Your score is: " + score);
} else if (score === 1 || score === 2) {
  document.write("You got silver crown! Your score is: " + score);
} else {
  document.write("You didnt get any crown.. :(");
}

I'm not familiar with the video you're referring to, but the only thing I can see that might cause issues down the road is if there are more questions added to where you get more than 5 points, you would get the "You didn't get any crown... :(" response. might be simpler to make it :

if ( score >= 3 ) {
    document.write("You got the golden crown!!! Your score is: " + score)
} else if (score === 1 || score === 2) {
  document.write("You got silver crown! Your score is: " + score);
} else {
  document.write("You didnt get any crown.. :(");
}

By checking value ranges instead of specific numbers, the method in the video helps keep the code compact, and supports possible future modifications (as Jeff suggested):

if ( score >= 3 ) {
    document.write("You got the golden crown!!! Your score is: " + score)
} else if ( score >= 1 ) {

Each test needs no high limit check because the previous "if" would have caught it.

I have only 5 prompt questions so it cant be more than 5 questions. Do you still think I need to use code like Jeff said or if there are no more questions than 5 then I can use my code?

It won't make much difference with only 5 questions and three categories, certainly none that would impact the operation of the program.

But it might be good to develop a practice of using a method that would still be compact and efficient when you had 50 questions and 10 categories.
