In computer programming, an event handler is a callback subroutine that handles inputs received in a program (called a listener in Java and JavaScript). ... Event handlers are a central concept in event-driven programming.
In computing, an event is an action or occurrence recognized by software, often originating asynchronously from the external environment, that may be handled by the software. Because an event is an entity which encapsulates the action and the contextual variables triggering the action we can use the acrostic mnemonic of an event as an "Execution Variable Encapsulating Named Trigger" to clarify the concept. Computer events can be generated or triggered by the system, by the user or in other ways. Typically, events are handled synchronously with the program flow, that is, the software may have one or more dedicated places where events are handled, frequently an event loop.
