What is the purpose the brackets []?

This question was already asked, but my question is still not resolved. Why isn't:

var questionsLeft = questions + " left";

also acceptable?

They don't serve any purpose beyond styling the output. They are in no way essential. If you prefer not to include them then that won't affect anything but how it looks when it is printed out.

Dave wanted the output to look like this:

[x questions left]

With your code it will look like this:

x left

In both of these examples x is a placeholder for the number of questions.

So to answer your question more directly, both would be equally acceptable. In programming there is rarely (almost never) only one acceptable way of doing something. And that is especially true when it comes to how you style output from your program, as styling is an inherently opinion driven thing.
