PLEASE make more videos like this! This walk through was so incredibly helpful! Honestly I would like videos this for the entire JavaScript course. I am over half way done with the JavaScript course on Codecademy and was starting to feel a little overwhelmed by new information and this was the perfect review before continuing on. I only wish the videos kept going to where I'm at in the course towards the end. Thank you!

Where can I find the next lesson?

I still can’t wrap my head around the ++ and -. How come when you were first using them in the postfix version (before it was even revealed there were two different versions) and also with the num++ they seemed to work as normal (simply adding 1 or subtracting 1) but as soon as you started using ++prefix and postfix++ that seemed to change?

Hey Marc! Great question. If you take a look at the examples when it was first introduced, in comparison to when we walk about postfix and prefix in the FAQ, the main difference is that in the earlier example, we were not assigning the result of the operator to a new variable.

When using num++, the current value of num is first output (at the moment of the call), and then one is added to this value. So, in the case when num is equal to 10, it will first output 10, and then num will increase to 11 (but new value isn't logged into console because previous values was). To output the incremented value, you can use the prefix increment form - console.log(++num);, then it will output 11.
