Interactivity and liveness in programming deserves to be discussed far more often than it is on front-page of hacker news, but excited there are multiple ongoing threads!

I'm a very strong supporter of interactive blogposts as well. Obviously https://ciechanow.ski/ is leader here - being able to mess with something to build intuition is huge.

Agreed. ciechanow.ski has been a huge inspiration, as well as 3blue1brown, Bret Victor, and Chris Granger (remember Light Table?). But none of them provide a way to walk through thousands of lines of real code and show how it is built and evolves over time. That is the key problem Scrimba and CodeMic are trying to solve.

The two people I have seen who really master this are Robert Nystrom (Crafting Interpreters) and Casey Muratori (Handmade Hero). But even they are limited by the mediums they use: books and videos, which are not ideal for this kind of guided exploration.
