- A programming paradigm in which data changes automatically propagate through a system, triggering updates to dependent computations or UI elements without explicit imperative code. In web frameworks like Vue.js, React, and Svelte, reactivity enables the user interface to automatically re-render when underlying state changes, typically implemented through mechanisms like observable properties, signals, or virtual DOM diffing. Reactive systems maintain dependencies between data and the code that uses it, ensuring consistency without manual synchronization.
