   • Event-Driven Programming Paradigm in Logic Programing

     Event-driven programming should be similar to how it is done in other languages, you would set up some framework to generate the events and you would call a goal to handle the event, possibly using the system's multithreading facilities (which leads to interesting aspects of transactions on the Prolog database, global vs. thread-local storage etc.)

     Paulo Moura would certainly provide this link to the Logtalk Manual:

   • What is the Event Driven Programming Paradigm ?

     Event-driven programming is a paradigm where the execution of a program is determined by events such as user actions or messages. Programs respond to events with predefined actions, allowing for asynchronous and responsive behavior, often seen in GUI applications and distributed systems.

     Advantages of Event-Driven Programming Paradigm

     • Enables asynchronous processing, optimizing resource utilization and responsiveness, crucial for real-time applications and user interfaces.
     • Encourages modular code design, simplifying maintenance and scalability by separating concerns and promoting code reusability.
     • Enhances user experience by responding promptly to user inputs, delivering a smoother and more interactive interface.
     • Facilitates easier integration of new features or modifications, promoting adaptability to changing requirements in dynamic environments.

     Try this. Add onkeyup event on the <textarea> tag then replace event.target to textareaElement to get the value

     var textareaElement = document.getElementById("userName");function updateCount() { document.getElementById("stringLength").innerHTML = textareaElement.value.length;}

     <label for="userName">User name:</label><textarea id="userName" onkeyup="updateCount()" cols="40" rows="3"></textarea><br><p id="stringLength">0</p>

   • Event driven vs sequential programming

     Top Answer

     Answered Dec 03, 2009 · 11 votes

     Two different methods to support two different needs. If you have a problem driven by events, then you should use an event-driven methodology. If you need to perform procedures on defined data, but you're not worried about what's happening elsewhere, then obviously you want to use a more "sequential" style.

     Note that typically, these two things are combined. A program's startup, shutdown, and maybe a main processing loop (say, a filter processor in an image app) will be largely sequential, while its UI layer and component interactions are event-driven.

   How does event-based programming work?

   • In event-based programming, determining the state and performance of the system is very straightforward. If the number of events in your queue—also known as queue depth—grows, then you need more consumers. If your consumers are sitting idle, waiting to process events, then your producers are not sending events.

   What is event based programming?

   • Event-based programming is an incredibly useful paradigm, with use cases ranging from UI in a single-process system to communication between services in large-scale distributed systems. The loosely coupled nature of event-based programming provides many benefits, though it may require a shift in how you think about inter-object communication.

   Mar 29, 2021 · Event-driven programming is an approach to programming that focuses on delegating events to matching event handlers. An event can take the form of a button click, a message being passed between a thread or program, or any other action within a system that can be abstracted into an "event".

   Nov 8, 2022 · Event-driven programming, or event-oriented programming, is a paradigm where entities (objects, services, and so on) communicate indirectly by sending messages to one another through an intermediary. The messages are typically stored in a queue before being handled by the consumers.
