What is Functional Programming ? Functional Programming or FP is a programming paradigm that is built upon two main concepts immutability, and statelessness.The goal behind FP is to make your code more readable, reusable, and portable. What is Functional JavaScript There has been a debate to ca...

Functional programming is a programming paradigm which models computations (and thus programs) as the evaluation of mathematical functions. It has its roots in lambda calculus, which was developed by Alonzo Church in his research on computability. Functional programming has some interesting conce...

A function in the *apply family is an abstraction of a for loop. Compared with the for loops *apply functions have the following advantages: Require less code to write. Doesn't have an iteration counter. Doesn't use temporary variables to store intermediate results. However for loops are m...

There is no inherent answer in C# to this - so called - need. Nonetheless there are workarounds to satisfy this need. The reason I qualify the need as "so called" is that we only need methods with 2 or more than 2 values to return when we violate good programming principals. Especially ...

CREATE [OR REPLACE] FUNCTION function_name [ (parameter [,parameter]) ] RETURN return_datatype IS | AS [declaration_section] BEGIN executable_section [EXCEPTION exception_section] END [function_name];

AutoHotkey used to heavily rely on labels until version 1.1.20. It's reliance on labels had very serious disadvantages. The main one being that labels usually execute in the global scope meaning that any variable defined within a label will be globally available. This sounds great until you realiz...

A normal function is never related to a function template, despite same name, same type. A normal function call and a generated function template call are different even if they share the same name, same return type and same argument list

Function composition operator (.) is defined as (.) :: (b -> c) -> (a -> b) -> (a -> c) (.) f g x = f (g x) -- or, equivalently, (.) f g = \x -> f (g x) (.) f = \g -> \x -> f (g x) (....

AutoHotkey comes with many built-in functions and variables which can be used anywhere inside a script. For a full list including explanations, see: List of built-in variables List of built-in functions

Higher Order Functions are functions that take functions as parameters and/or return functions as their return values.
