Functions & Methods

Functions and methods are fundamental building blocks for organizing and reusing code. A function is essentially a block of code that performs a specific task. You give it some input (arguments), and it returns an output (return value). A method is very similar to a function, but it's associated with an object or class. It operates on the data within that object or class. In practice, the distinction between functions and methods in Scala is often blurred, but the key is they both allow you to break down complex problems into smaller, manageable pieces.
