Quick javascript question...

[Ricemarine]

A. "Today is ' + day1
B. "day1: " + day1 + '; week1: ' + week1
C. day1 " + " week1
D. "day1" " + " "week1"

This makes no sense to me because with my current knowledge (hoorah for entry level computer science?) none of them are correct. Yet those are the only options...

Am I right?

Otherwise it'd be just a literal expression and the answer would be D. The question asks for a valid string expression when day1 and week1 are variables.

NM: Didn't see it at the end of the OP

Wait, nm, the answer is B. You can use ' or " on the same line IIRC, but a single quote can't close a double quote and visa versa

I can't read letters apparently. 😛

A: Invalid can't mix ' and "
C: There is no concatenation operator since the + is in quotes
D: No escape characters for the "

I'd say A.
Maybe B, but either way, it's sloppy and should be discouraged.

Definitely not D, you fail.

Why is B invalid?

The answer is c

I guess that makes sense too.

Was thinking about the apostrophes... It seems possible, just that we were never taught to use them... Rather not take a chance since this is due at the end of the day tomorrow and ask the professor to see if any typos were actually made.

Thanks guys 🙂

B is closest to valid, assuming week1 is a declared variable. I'm not sure about mixing single and double quotes in the same expression though.

You are allowed to, I've tried it 🙂.
