LISP was the first functional programming language, followed by Erlang, Scheme, Haskell, OCaml, Scala, Clojure, F# and others. Copyright © 1981-2019 byThe Computer Language Company Inc. All Rights reserved.
Definition Functional Query Languages came from two lines of development: 1. From new functional programming languages such as FP that showed the value of referential transparency ; this ensures that complex nested functional expressions can be evaluated inside-out (bottom-up) or top-down or even ...
Functional programming is programming with mathematical functions.I think you already guess it. The key to this definition is the mathematical expression function. Mathematical functions are functions that return every time the same result when given the same arguments. They behave like an infinite big...
A functional language is a programming language built over and around logical functions or procedures within its programming structure. It is based on and is similar to mathematical functions in its program flow. Advertisements Functional languages derive their basic structure from the mathematical frame...
(Read Straight From the Programming Experts: What Functional Programming Language is Best to Learn Now?) To better understand this distinct class of programming languages, we’ll look at the definition, characteristics, and the history associated with it. (Check out INFOGRAPHIC: The History of ...
and you see that inFigure 5. The rec in the definition of eval is necessary to tell the F# compiler that eval will be invoked recursively within the body of the definition. Without it, F# will be expecting a local nested function named eval to be present. I use the function getVarValue...

It’s surprisingly hard to find a consistent definition offunctional programming. As just one example, some people say thatfunctional programming (FP)is about writingpure functions— which is a good start — but then they add something else like, “The programming language must be lazy.” Really...
功能语言主要由函数组成,强调程序的语义而不是编译。功能语言没有传统命令式编程风格的副作用,因为函数式语言不会改变程序的状态,并且在使用相同的参数传递函数之前将返回相同的结果。 来自<https://www.techopedia.com/definition/19505/functional-language
and often underlies the structured programs most developers learn to write in the early stages of their career. Many of these languages include elements that are almost indistinguishable from functions, but they're a far cry from the mechanisms found in a purely functional programming language like...
