Question re: syntax (JavaScript Mad Libs Challenge Revisited)

Question

Hello all! :)

I just completed the Mad Libs Challenge Revisited project, and it worked, but I have a question about the syntax because there's something I'm not clear on.

it's in this portion:

questions -= 1;
questionsLeft = ' [' + questions + ' questions left]'; ```

I was wondering about the apostrophe/quote marks. My understanding is that when you use quote marks, and then have to nest additional quote marks inside them, you should use them in sets of ' ' and " ", so the program won't get confused. A ' will close the last ' that was entered, and a " will close the last ". So under that logic, in this snippet of code, it seems like the first ' should close right after the [.... but I guess that's wrong in this case? Can anyone explain to me what's going on with this? Thank you for taking the time. :)

You're absolutely correct. In this case, we actually do want to close that string right after the [ then concatenate what the questions variable is equal to (instead of the actual word "questions") to the string, then concatenate the rest of the string to the end of that.

So if you had something like

var questions = 7;
questions -= 1; 
var questionsLeft = ' [' + questions + ' questions left]';
console.log(questionsLeft);

The console would log: [6 questions left]

Since in this case: questions === 6.
