What other paradigms and approaches to software development have you used besides object-oriented programming?

In addition to object-oriented programming (OOP), I have applied the following paradigms and approaches:

• Functional programming: using pure functions, immutable data, and higher-order functions. For example, in C# with LINQ, you can write code in a functional style.
• Procedural programming: sequential execution of procedures and functions, which is convenient for simple tasks and scripts.
• Event-driven programming: handling events and callbacks, often used in UI development and asynchronous systems.
• Component-based approach: dividing the system into independent components with clearly defined interfaces.

Example of functional style in C#:

var numbers = new List<int> {1, 2, 3, 4, 5};
var evenSquares = numbers.Where(n => n % 2 == 0).Select(n => n * n);
foreach(var num in evenSquares) {
    Console.WriteLine(num);
}
