993 Pointsthe Meaning of '['questions+'questions left]'???
I saw someone said to treat '[' and ']' as strings, but if you write the code like : questions+questions left']' . It doesn't work!
could someone give me the official solution about this issue??

var questionsLeft = ' [' + questions + ' questions left]';
This creates a string that has brackets in it (assuming you already have a variable named questions), which will be printed out later. Anything enclosed in quotes is a string.
Brackets by themselves (not in a string) are used for indexing. I expect that will be covered later in the course.

14,943 Pointsquestions left is a string and a part of the sentence -> it must be inside of quotes. Only questions is outside of the quotes, because it's a variable.

993 PointsThank you Steven, but if I treat it as string, and put the third quote just in front of the second bracket like this
var questionsLeft = ' [' + questions + questions left ' ] '; this code doesn't work anymore. why?
