Function declarations and returns

A function starts with its name, not a function keyword. Parameters are typed, -> names the return type, and a missing return type means void.

Use small named functions to make actions and transformations obvious and testable.

Name(Type parameter) { ... }
Name(Type parameter) -> ReturnType { return value }
