Event Handling
Event handling is a programming paradigm that enables software to respond to user actions, system events, or external triggers in real-time. It involves defining event listeners or handlers that execute specific code when an event occurs, such as a mouse click, keyboard input, or network request completion. This concept is fundamental to interactive applications, including web development, desktop software, and mobile apps.
Developers should learn event handling to build responsive and user-friendly applications that react dynamically to user interactions and system changes. It is essential for creating interactive features like form validation, button clicks, drag-and-drop interfaces, and real-time updates in web and mobile development. Mastering event handling improves code organization and performance by decoupling event logic from core application flow.
