I assume your friend thinks youâre batty because of your beverage opinions and not for other reasons beyond my expertise. Given that, Iâd have to side with your Perrier-drinking pal, but also assure you that it is a common misconception that carbonation pulls calcium from your bones.
Functions [edit]. A function, which can also be referred to as subroutine, procedure, subprogram or even method, carries out tasks defined by a sequence of statements called a statement block that need only be written once and called by a program as many times as needed to carry out the same task.
Functional programming (often abbreviated FP) is the process of building software by composing pure functions, avoiding shared state, mutable data, and side-effects. Functional programming is declarative rather than imperative, and application state flows through pure functions.
