Is it normal to code along to videos or it better to watch the video fully and take notes?

Whatever works best for you.

I usually code along w the video and take notes too (usually in the comments of my code)

Whatever u find works before for you however

Amen on the "whatever works for you" route.

You gotta learn how you learn best.

This is my story with introductory videos:

I used to just take notes, but my brain simply wasn't retaining the information because it wasn't engaged enough. I've seen that the more I give to my brain to learn, the better it is at remembering. So whenever I try to remember I only think what my notes say "function A uses argument B which is a number"

I changed my strategy to coding along with the video + give it my own edge cases. "Can I use floats? Oh no because internally it's using a for-loop." Thus, my brain remembers "function A uses argument B, which must be an integer, not a float, because it uses a for-loop. I used it 3 days ago in file `trying_func_A`". It's a slower process but better for long-term stuff

Code along with the video, by doing so you will detect the errors and bugs yourself..
