814 PointsQuestion about closing quote on Line 2 - confused
Hi there - just wondering about the opening and closing quote marks on this line 2?
var questionsLeft = ' [' + questions + ' questions left]';
specicially the ones here [' + questions +'.....
why are we dividing the line like this?
Cheers

243,670 PointsThis is an example of concatentation, which is what the plus-sign operator (+) does with strings. Some of the parts being joined together are literal, and those are enclosed in quotes. This first is just a bracket ('['), the last is some words and a closing bracket (' questions left]'). Sandwiched in between the value of the variable questions.
So, if questions contained the number 7, or the string '7', after this assignment questionsLeft would have this string in it:
[7 questions left]
Does it make sense now?
