This article explores the push-pull algorithm behind Signals, a reactive programming concept used in modern frontend frameworks like Solid and Vue. It explains how Signals create a system where derived values automatically update when their dependencies change, similar to spreadsheet functionality. The piece provides technical insight into the core mechanism that enables efficient reactivity in contemporary web development.
Background
Signals are a reactive programming concept used in modern JavaScript frameworks to efficiently manage state changes and automatic UI updates. The push-pull algorithm optimizes how dependencies are tracked and updates are propagated through the system.
