💡 Dennis Dietrich takes you through the process of integrating functional programming concepts into your existing object-oriented programming (OOP) codebase. While traditional OOP methods dominate most legacy codebases, Dennis focuses on introducing functional concepts such as pure functions, closures, higher-order functions, and immutability. He offers real-world applications of these concepts, demonstrating how functional programming can coexist with OOP and improve maintainability, readability, and performance without needing to rewrite your codebase from scratch.

📩 6 Things You’ll Learn:
1. How functional programming can enhance your object-oriented codebase
2. The importance and implementation of pure functions and immutability in practical applications
3. The difference between first-order and higher-order functions
4. How closures relate to functional programming and their real-world applications
5. Why functional programming leads to better testability and thread safety
6. Practical examples, including exception handling and synchronization in functional style
