Why is 'captionText' not put as a jQuery representation? In other words why doesn't it have a $ sign next to it?

Caption text isn't a JQuery representation of an object, It's a simple string, no more. If you want to see it alive I setted up this little jsfiddle. Just open your console by pressing F12 and run the code. This will become obvious then.

captionText is a variable that's value the text of the clicked image's alt attribute. Therefore, it doesn't need to be a jQuery object.

I have answered another question from this lesson that may be a tangent of this question. Perhaps it may help make things a little more clear.
