In August of last year, a v0 draft of a proposal for signals in TC39 was publicly released, along with a spec-compliant polyfill. Signals enable one-way data flow by modeling cells of state and computations derived from other state/computations. Each node in the acyclic graph can be clean or dirty. By combining an acyclic graph data structure with a push then pull algorithm, advantages like automatic memoization and lazy evaluation of computations arise. Signals provide a way to manage state in a more structured and efficient manner compared to traditional function composition. Overall, signals offer a powerful tool for managing state in complex applications.
