Functions in SNOBOL
Functions in SNOBOL look unlike functions in almost any modern language. There is no def, function, or return-type keyword. Instead, a function is created at runtime by calling the built-in DEFINE, …

Functions are the heart of Standard ML. As a functional language, SML treats functions as first-class values: they can be bound to names, passed as arguments, returned from other functions, and stored …
Read more →Functions are the primary building blocks of reusable logic in Swift. A function packages a piece of behavior behind a name, accepts typed inputs, and produces a typed output. Swift’s static, …
Read more →In Ruby, the unit of reusable behavior is the method. Because everything in Ruby is an object, what other languages call a “free function” is really a method defined on an object—and a …
Read more →Functions are the building blocks of every Rust program—you have already met main, the special entry point. Beyond main, functions let you name a piece of behavior, give it typed inputs and a typed …
Functions are where Scala’s dual nature really shines. As a language that unifies object-oriented and functional programming, Scala treats functions as both named blocks of behavior (methods, …
Read more →In most languages, functions are a feature. In Scheme, functions are the whole point. As a member of the Lisp family with a deeply functional core, Scheme treats procedures as first-class values: they …
Read more →Most languages have standalone functions you call by name. Smalltalk does not. In a pure object-oriented, message-passing language, the closest thing to a “function” comes in two flavors: …
Read more →RPG is a procedural language, and it offers two distinct mechanisms for organizing reusable code: subroutines and subprocedures. Understanding the difference between them is central to writing modern …
Read more →Functions are how Python programs are organized into reusable, named blocks of logic. Instead of repeating the same code, you wrap it in a function, give it a name, and call it whenever you need it. …
