single quotes outside wrapping square brackets

I worked through this lesson and everything makes sense except the funky single quotes surrounding the opening square bracket and then again outside the closing bracket on the questionsLeft variable throughout the script. I don't understand what they're doing there? Check out lines 2, 5, and 8. Anyway if someone could help me understand what the purpose is that would be great! https://w.trhou.se/26gx4yla5o

The brackets aren't part of the code in this instance. They're a part of the string that will print something like this [3 questions left]

so the brackets are just there to help separate things visually?

Yes, it's to format the output a certain way for the user. This was the Teacher's personal preference but you can do something else if you want.
