What are some alternatives to nested conditionals in programming?

There are several alternatives to nested conditionals, such as using polymorphism, strategy patterns, or guard clauses.

Can you explain how polymorphism can help reduce nested conditionals?

Sure! Polymorphism allows you to define a common interface for different classes, enabling you to call methods without needing to check the type explicitly.

What is a strategy pattern?

The strategy pattern is a behavioral design pattern that enables selecting an algorithm's behavior at runtime, which can help avoid complex conditional logic.

How do guard clauses work?

Guard clauses are early exits in a function that handle special cases, allowing the main logic to remain clear and reducing the need for nested conditions.

Can you give an example of using guard clauses?

Certainly! Instead of checking multiple conditions, you can return early if a condition is met, simplifying the flow of your function.
