 Event-driven programs can be written in any programming language, although the task is easier in languages that provide high-level abstractions, such as await and closures.Because the code is for checking for events and the main loop are common amongst applications, many programming frameworks take care of their implementation and expect the user to provide only the code for the event handlers.In this simple example, there may be a call to an event handler called OnKeyEnter() that includes an argument with a string of characters, corresponding to what the user typed before hitting the ENTER key.
