MadLibs Challenge Syntax Explanation - Use of quotes and plus sign

Why does + sign go in between the quotes in below? var questionsLeft = ' [ ' + questions + ' questions left] ' ;

Could someone interpret this syntax step by step?

1 Answer

Although I haven't done the JS courses yet, I'd assume the reason it's set up this way is that the variable questionsLeft is assigned the opening square bracket "[" then the contents of the variable questions (+ questions) and finally assigned the string questions left] (+ "questions left]". That way when you call the variable questionsLeft later it will spit out to the screen something like "[5 questions left]".

I hope that cleared things up a little bit.
