👉 Handlers in programming refer to functions that are called when a user interacts with an application. These functions take parameters and return values, but they don't directly interact with the application's data or state. They are often used within the context of event handling, which is a type of programming model where the application is designed to respond to user interactions by executing specific code actions based on the input received. Handler functions allow developers to define how an event should be handled in response to user input or other events.
