Event-Driven Programming Test Questions
Course Introduction
Event-Driven Programming introduces students to a programming paradigm centered around responding to events or user actions, such as mouse clicks, key presses, or messages from other programs. The course covers core concepts including event loops, listeners, handlers, and callback functions. Students will learn how to design modular and interactive applications by properly structuring code to handle asynchronous operations and real-time interactions. Through hands-on projects and practical examples, learners will explore the implementation and management of events in various environments, with an emphasis on commonly used frameworks and languages such as JavaScript and Python. By the end of the course, students will be able to create responsive applications that effectively handle dynamic user input and system events.
