🔒 Immutability
Data doesn't change after creation.
Functional Programming
Functional programming treats computation as the evaluation of mathematical functions, emphasizing immutability and avoiding state changes.
✨ Pure Functions
Functions with no side effects that always return the same output for the same input.
🔗 Function Composition
Building complex operations by combining simpler functions.
📦 Higher-Order Functions
Functions that take or return other functions.
