Equally good to use .toLowerCase() instead of .toUpperCase()?

Hi

I see you always use .toUpperCase() for checking user input.

I find it cleaner to use .toLowerCase() and check (for example) for answer === 'hypertext markup language' instead of answer === 'HYPERTEXT MARKUP LANGUAGE'

Is there any reason except for preference that you use .toUpperCase()?

Like, are some uppercase characters not converted correctly when you use .toLowerCase() while everything works correctly when converting lowercase characters to uppercase?

Thanks in advance

You are correct Kenny Brijs. It's just a preference, which you choose, for these examples. toLowerCase() is just as good for making a comparison like this. Good job thinking through this question!
