Key Improvements

Dynamic Attribute Handling: By using setAttribute, this method handles any valid attribute.

Event Listeners: You can define event listener functions conveniently by prefixing them with listener.

Cleaner Code: The improved function eliminates the need for a long list of parameters, making it more maintainable.

Conclusion

Creating a function to generate HTML elements dynamically is a powerful way to improve your web applications. With the cEl function, you can easily create elements with various properties without cluttering your code. Whether you're developing a small project or a larger application, this approach will streamline your HTML manipulation tasks significantly.

Feel free to experiment with the function and expand its capabilities to suit your development needs. Happy Coding!
