What people who prefer videos wont admit is they just find it more comforting to have someone instructing them. Especially if they left an impression on them previously. It's lonelier and harder to establish a connection through blog posts so they will sit through videos instead.

Not entirely true. How would you teach a course like "Ship your 1st iOS App from Scratch". It involves lots of different things that you can't do just with Audio. Like I said, Audio-only instructions works only for simple scripting stuff like batch files, or client side scripting / coding like Javascript (which is what OP's example is in) and HTML, CSS etc.

ETL tools like Informatica, SSIS etc also need a visual, otherwise you get quickly lost. And how will the instructor do it in just audio "Oh, on left you will see a toolbox, look and locate the one that looks like a grid, but not the one that has an X on top right, also not the one that has a red cylinder icon at the bottom."

The 1 caveat I see in video instructions is that you have to constantly pause the video and code and then un-pause again, if you are following along with the coding. I get around that with the dual monitors.

I do find it more comforting to have someone instructing me, but in the context of being in a class or group of people who also are learning with me.
