event-driven programming

Event-driven programming is a programming paradigm where the flow of the program is determined by events, such as user actions (like clicks or keyboard input), sensor outputs, or messages from other programs. Rather than following a strict sequence of commands, the program waits for these events to occur and responds accordingly. This approach is common in graphical user interfaces (GUIs) and real-time systems, allowing for more interactive and responsive applications. Essentially, the program reacts to happenings in the environment, making it flexible and adaptable to user needs.
