5 Advantages and Disadvantages of Event Driven Programming | Limitations & Benefits of Event Driven Programming

 

Software is created using the Event Driven Programming (EDP) paradigm, which bases software development on events. Events could include anything from user communications. Examples include utilizing the microphone, clicking mouse buttons, and inputting text using a keyboard. It may also occasionally be generated by a program.

The software responds with a callback function when it detects events. This is made possible via a primary loop that is continuously running. Today's most popular programming languages provide event-driven programming. 

One such language made to handle an event-driven approach is Visual Basic. Java and Python can also be used for this. Almost all software built nowadays follows the event driven programming methodology. User events serve as the foundation for all of their functions.

Event-driven programming does not involve the computer performing predefined tasks. Rather, there is a Graphical User Interface (GUI) with several settings. A user's continuous engagement with the software is ensured via event-driven programming. For this reason, this concept is preferred by many firms. In addition, the end users gain from a superior product and an improved interface.

There are a few techniques to increase the efficacy of event driven programming if you decide to use it. They aren't faultless, though. You can decide if event-driven programming is the best strategy for your company by examining the benefits and drawbacks of the technique.

I'll be talking about the 5 Advantages and Disadvantages of Event Driven Programming | Limitations & Benefits of Event Driven Programming. You will learn about the pros and cons of event-driven programming from this post.


Now let's get started,

Advantages of Event Driven Programming

1. Simplicity

Event driven programming is more user-friendly than other forms of programming languages. When a business requirement is there, the program can be developed without difficulty.



2. Convenience

An additional aspect of event driven programming is predictive coding. Predictive coding is made feasible with the aid of languages like Visual Basic. The pertinent recommendations appear as the developer types the code.



3. Flexibility

Event-driven programming does not follow a set sequence from beginning to end. The code may be easier to execute in this order. Furthermore, this is the kind of code that may be changed as needed. The code is adaptable and can be altered if there are requirements or coding issues.



4. GUI Support

Event driven programming provides a pre-programmed toolbar in the form of a Graphical User Interface (GUI). It is possible to develop additional interactive applications from this toolbar. For instance, there are already tools like radio buttons.



5. Power Consumption

Hardware interrupts are used in event-driven programming implementation. Consequently, a significant reduction in power consumption occurs.

Disadvantages of Event Driven Programming

1. Speed

As GUIs are the foundation of event-driven programming. Overall program performance is decreased. particularly if there is not enough installed RAM.



2. Complexity

Simple programs cannot handle the complexity of event driven programming. The program flow and stack management are the main factors contributing to the complexity of EDP. It is worthwhile to think about other solutions, such as batch programming, if the software is tiny.



3. Resource Utilization

The main loop, which is used in event-driven programming, is known to use system resources. because the main loop runs in the background continuously. Furthermore, EDP is unable to offer an interface until the necessary requirements are fulfilled because of the use of GUI.



4. Language Translation

You cannot translate a program written in the EDP language to another language once it has been written. because event-driven programming is the only way some features, like buttons, can be written to function.



5. Platform Support

Event-driven programming is typically platform-specific. A software that makes use of EDP is incompatible with other systems. 

 

For instance, Windows library files are used by the Visual Basic program. The software won't find these files if it is relocated to a different operating system.
