Signals: The Backbone of Reactivity
Signals serve as a directed data graph in the world of reactivity, allowing multiple signals to listen to each other and run effects accordingly. These data dependencies create a system of predictability where changes trigger updates only once, ensuring a stable and synchronized data flow. Signals have gained popularity among various frameworks like Angular, Vue, and Svelte, leading to a standardized proposal for signals integration in JavaScript, offering potential benefits for debugging, tooling, and graph visualization in web applications.
