An Animated Guide to Ember Internals
summary
Animated walkthrough shows how Ember compiles wire format into opcodes, executes an append VM for initial render and an update VM for patches, and uses a ticketed cache so many reference recomputations are skipped. It demonstrates classic action vs closure action mechanics: classic registers an action state and delegates clicks via a body handler (defaulting to 27 event types), while closure actions attach a direct onclick function. Concrete numbers, opcode names, the action registry, and the run loop scheduling are all shown and animated.
