functionevent
Functionevent is an informal, non-standard term used in software engineering to describe a concept at the intersection of functions and events. Because it has no universal definition, its meaning varies by context. Broadly, it refers to a pattern in which function execution either produces events or is itself treated as an event source.
As a source of events, a function can emit one or more event payloads during its execution.
As a wrapper or data structure, a functionevent may be a value that encodes the intended event
In practice, the term is used in various contexts: in JavaScript or front-end frameworks to describe events
Advantages include improved decoupling, testability, and explicit event payloads; limitations include potential overhead, model divergence, and
