Who invented functional programming?

John McCarthy
The first high-level functional programming language, LISP, was developed in the late 1950s for the IBM 700/7000 series of scientific computers by John McCarthy while at Massachusetts Institute of Technology (MIT).

What is monad in oops?

In terms of OO programming, a monad is an interface (or more likely a mixin), parameterized by a type, with two methods, return and bind that describe: How to inject a value to get a monadic value of that injected value type; How to use a function that makes a monadic value from a non-monadic one, on a monadic value.

Where do monads come from?

“Monad” comes from the Greek word monas , which means a unit, individual, atom… something that is indivisible. Monads combine to form compounds, which make up the matter we interact with in the world.

What programming paradigm is SAS?

procedural programming language
SAS is a procedural programming language. (So are FORTRAN and C.) SAS programming tends to be action-oriented. The procedure (or SAS/IML module) is the “unit” of programming.

What is the history of Monad programming?

History. The term “monad” in programming actually goes all the way back to the APL and J programming languages, which do tend toward being purely functional. However, in those languages, “monad” was simply shorthand for a function taking one parameter (a function with two parameters being a “dyad”, and so on).

What are monads in functional languages?

Monads in Functional Languages 1 Monad is a workflow composition pattern 2 This pattern is used in functional programming 3 Special syntax helps simplify the usage

Do you need category theory to use the monad pattern effectively?

The monad has friends which are also borrowed into programming: monoids, functors, and applicatives. Although the math is important and valuable I think the monad pattern can be used effectively without knowledge of category theory, just as a programmer can effectively use the lambda -functions without understanding

What is a monad in lambda calculus?

In the lambda calculus, the body of a function is a single expression. Complex expressions can be created by composing functions. As we will see later, monads provide a solution to a problem that can arise when we compose functions. Before going on, let us therefore see variations of using function composition in different environments.
