Forget OO and Think Functionally!
summary
Introduces functional programming as an alternative to object-oriented thinking, explaining core ideas of functional languages and how they change program design. Covers functional programming concepts and compares them with OO, illustrating how to approach problems using functions, immutability, and declarative patterns.
