Haha, I tried to use "Fluffy the Cat" as a variable name. Didn't end well.

I tried to use "my variable" but it didn't work. Guess spaces aren't allowed.

I think we had a similar question in our last quiz, and I remember something about reserved keywords. We should avoid those!

I’m not entirely sure, but I feel like "myVariable" is a valid name. I hope I’m remembering that correctly!

I remember we practiced a question about valid variable names, and I think they can include letters and underscores.

I think variable names can’t start with a number, right? So maybe something like "var1" wouldn’t work.

I feel pretty confident about this one. The valid variable names are probably "myVariable" and "x123". Anything with spaces or special characters wouldn't work.

Okay, let me think this through. Variable names need to start with a letter or underscore, and can only contain letters, digits, and underscores. So I'd say "myVar" and "var_123" are probably the valid options here.

Ugh, I hate these syntax questions. I always get tripped up on the specific rules for variable naming. I'll just have to guess and hope for the best.

Hmm, I'm not totally sure about this. I know variable names can't have spaces, but I'm not sure about other rules. Maybe "my_variable" and "variable123" could work?

I think I know the answer to this one. Variable names can't have spaces or special characters, so I'd say the valid options are "myVariable" and "x123".
