Is Au3 a type of functional programming language?

Is Au3 a type of functional programming language? I know it's a style of programming not a language... but I find Au3's libraries/UDFs to be more function centric focused than most other languages.

I don't think so, functional programming is more related to using pure mathematics than using "functions", it is easy to confuse both because function can mean different things depending on the context. Haskell would be a good candidate for a functional programming language I imagine.

I think you are looking for the term "Procedural", which correctly matches the Functions we use in AutoIt, sometimes functions are also called procedures, bits of code which can be called to perform a procedure :). Most BASIC-like languages are procedural programming languages.

The other kind of programming languages are called Object-oriented (programming) languages, but I am guessing you are already familiar with that. Some BASIC-derivatives have added support for these OOP features.

Hmm I guess it depends on how a person uses Autoit. I generally use Autoit to save time on calculating mathematical equations..

Not at all. being a functional/object-oriented/imperative/whatever is a given language property, forcing a programming paradigm.

That you use an imperative language like AutoIt to solve math equations using functions doesn't mean AutoIt is a functional language. See Erlang, Haskell, Mathematica and many others for that.

"Procedural programming (PP), also known as inline programming takes a top-down approach. It is about writing a list of instructions to tell the computer what to do step by step. It relies on procedures or routines. ... Functional programming (FP) is about passing data from function to function to function to get a result."

https://medium.com/@LiliOuakninFelsen/functional-vs-object-oriented-vs-procedural-programming-a3d4585557f3#:~:text=Procedural programming (PP)%2C also,relies on procedures or routines.&text=Functional programming (FP) is about,function to get a result.

I don't see why Au3 can't be used for functional programming... my Au3 programs definitely don't use a "step by step"/"top-down approach". This is an exact representation of how my Au3 library works "In FP, functions are treated as data, meaning you can use them as parameters, return them, build functions from other functions, and build custom functions." But Some of my functions are mutable "Functions in FP have to be pure functions, they should avoid shared state, and side effects and data should be immutable"

Though some of my larger Au3 programs do contain mutable functions that rely on shared files. All of my functions are built on top of other functions & work in a non linear way with each other. I've never coded any type of functional language before but I have done a fair share of OOP python, vba, & other languages. I just wanted to know what type of programmer I have evolved into... hmm maybe something else entirely. I do prefer Au3 over other languages as I am way more productive.

No, FP is about composing functions as first-class citizens.

AutoIt knows nothing about λ-calculus, pure functions, composing functions, allows functions with side-effects.
With an FP language, functions can be computed, modified, examinated (introspection) all during program run.

If you try and you'll appreciate the fundamental difference.
