LOGO - it was this kind of graphics generation language where a cursor moved on the screen based on commands you put in. This clicked right away. I was 5 years old IIRC. Then, during my pre-teen years, I couldn’t understand how games had several moving objects all at the same time even though it was sequential execution. Then the update-render loop clicked in as I discovered it. Together with that, all kinds of event handling, interrupts, context switching etc. Then, with WPF, databinding really clicked in with any sort of retained-mode rendering. So then Angular, React etc as well.
