Object-Oriented Programming vs Functional Programming

Object-oriented programming (OOP) focuses on using objects to design and build applications, while functional programming (FP) emphasizes the use of pure functions and immutability.

Key differences between OOP and FP:

• Modularity: OOP emphasizes encapsulation and inheritance to achieve modularity, while FP focuses on composing functions to achieve modularity.
• Mutability: OOP allows mutable state, while FP promotes immutable data structures and values.
• Control Flow: OOP uses control structures like loops and conditionals, while FP relies on higher-order functions and recursion for control flow.

Choosing between OOP and FP:

When deciding between OOP and FP for developing a software application, consider the nature of the problem domain. Choose OOP for complex systems with interrelated objects and behavior, where modularity and code reuse are important. On the other hand, opt for FP for tasks requiring high levels of concurrency, parallelism, or mathematical computations, where immutability and pure functions are advantageous.
