Reactivity

Reactivity refers to a system’s ability to automatically update or respond when something changes. In programming, it means that when data or state within an application is modified, the system detects this change and updates the user interface or other related components instantly without manual intervention. This creates seamless and dynamic user experiences, as the displayed information always reflects the current data. Reactivity is fundamental in modern web development frameworks, enabling developers to build interactive apps that stay in sync with real-time data effortlessly.
