Downright the best zero-to-programmer course in the world. Wish I knew about it when I was starting out: https://online-learning.harvard.edu/course/cs50-introduction...

I can certainly vouch for CS50, when I was in middle school I messed around with programming, but taking CS50x was what made the intuition and process come together for me.

I've seen those first two on Reddit before, and they're amazing. They take the time to explain thoroughly but still remaining engaging with no special tricks. The use of physical models instead of diagrams (or Powerpoint slides) doesn't seem like it should be important, but it is.

The car differential video is genius. It confused the hell out of me for the first 2 minutes, but then it clicked beautifully.
