I haven't seen any of your videos so the following is only a general statement about tutorials.
For some such tutorials might be helpful, but the danger with such example/syntax tutorials are, that people will copy the code and will adapt what one teaches them, thus if you show a bad practice, it might end up in their code anyways and blow up at some point. Thus for me it would be important to explain the syntax and then discuss different techniques and show some good practices. Sure it's more time-consuming and one has to plan ahead, but in the long run the viewers will benefit more from it.
