Signals, the push-pull based algorithm

https://willybrauner.com/assets/signal-cover-meta.webp
Signals are a reactive programming paradigm that uses a push-pull based algorithm to propagate changes through a graph of dependent computations, allowing derived values to automatically update when their dependencies change. The algorithm combines a push-based approach where notifications are immediately pushed to subscribers when a signal is updated, with a pull-based approach where ...
