Why did we need to create the string '[3 questions left]' in the first place?

This step is really confusing to me. We were told to place it, we weren't told why we needed to place it then we were told to remove it?

Oh yeah I can see how that is confusing

He was making a reference to the type of string you were ultimately going to display.

This is an example of the string we want. that's all. '[3 questions left]'

var question = 3; var questionsLeft = '[ + question + 'questions left]';

Basically questionsLeft would print out to the screen as '[3 questions left]'

So once we finish creating questionsLeft variable. We can delete the example of how the variable will look.

A bit confusing but you are right. You don't need. He just put it there to help understand what the output of the string was going to look like.

Kinda like drawing a tattoo before getting it done. You use the drawing to help make the tattoo but once the tattoo is done you can toss the drawing.

Make sense?

+1 but in your line where you have code you are missing a ' beside the [ on the right side :P
