Event-Driven Programming
Event-driven programming is a programming paradigm where the flow of the program is determined by events such as user actions (e.g., clicks, key presses), sensor outputs, or messages from other programs. It uses event handlers or callbacks to respond to these events, enabling asynchronous and non-blocking operations. This approach is common in graphical user interfaces (GUIs), web applications, and distributed systems.
Developers should learn event-driven programming for building responsive applications that handle multiple concurrent operations efficiently, such as web servers, real-time systems, and interactive UIs. It's essential in modern web development with JavaScript frameworks like React and Node.js, where user interactions and network requests drive application behavior. This paradigm also supports scalable architectures in microservices and IoT systems by decoupling components through event messaging.
