Great video with some tips I have not heard before concerning seemingly trivial decisions that cause serious issues as projects get larger.
The creator is an experienced programmer but seems brand new to making videos. That said, apart from an annoying number of calls for action (‘leave a comment…’), it is well produced, especially for a first crack at the craft.
You’re right, this vid is aimed more at folks who have already learned the very basics & focuses on general practices that may seem obvious to beginners but cause serious issues once projects start to get more complex.
If you’re still working on learning the bedrock stuff, try this video again in a short bit, there’s some great tips.
