Event-Driven Programming

Event-driven programming is a programming paradigm where the flow of execution is determined by events such as user actions, sensor outputs, or messages from other programs. This model is widely used in graphical user interfaces (GUIs), real-time systems, and server-side applications.

At its core, event-driven programming relies on components like event listeners, which wait for specific triggers, and event handlers, which define the responses to these triggers. For example, clicking a button in a GUI can trigger a predefined function to execute.

Languages like JavaScript, Python, and C# are well-suited for event-driven programming due to their robust libraries and frameworks, such as Node.js and .NET. This approach enhances flexibility and responsiveness, making it ideal for dynamic, user-centric applications.

By decoupling event producers and consumers, event-driven programming allows developers to build scalable and efficient systems that adapt seamlessly to changing inputs.
