"Functional Programming is Overrated" "Lambdas leading to unreadable code" 20 years later: "Function programming sucks" "Functional Programming is Overused by web developers let's stop it" "Functional programming considered harmful" "Functional programming considered harmful considered harmful" Hopefully we won't be reading that on Medium. Object-oriented programming (OOP) as an idea has been oversold. Anyway, functional programming is overrated - its just procedural programming with a different style. Thus, programmers need not be highly familiar with the pure functional language paradigm to use OCaml. greydius on Aug 3, 2016. I consider many developers that consider themselves as "Object Oriented" (included myself), more like "multiparadigm oriented". OCaml unifies functional, imperative, and object-oriented programming under an ML-like type system. God I hate the term "code smell", but I can't think of anything more accurate. A Bit of Heresy: Functional Languages Are Overrated (2010) (benrady.com) ... (ML-style) functional programming does well, since it's basically a journal of a serious expert in object-oriented design learning switching over to the functional paradigm. There are languages that are purposely designed to be bizarre. Often times the less known the language the louder the zealots. So IMHO functional programming is not exactly declarative programming, but indeed functional languages are more declarative than procedural ones. I'm designing a high-level language & compiler to Whitespace in my spare time to learn about compiler construction, language design, and functional programming (compiler is being written in Haskell).. During the code generation phase of the compiler, I have to maintain "state"-ish data as I traverse the syntax tree. The most commonly-used languages in use today are designed around the idea of OOP. In general, this is an overrated topic of the software industry. Software Architecture is an important topic, but it’s overrated. That said, "purity" in FP is a totally overrated concept IMHO. Functional programming makes use of loose variables. This is the second part in a series I’m writing about lessons that can be learned from functional programming. Also, declarative systems are not overrated, but you need some dozen of years to develop them (read the mythical man month) Find the first part here. The most commonly used languages in use today are designed around the idea of OOP. As John points out, every single language has its zealots. Object Oriented Programming (OOP) as an idea has been oversold. Anyway, most functional languages can also make use of OOP, yet they are not really based on objects as JAVA where everything is an … Unless you compare C++ and Object Pascal developers with Java and C# developers, and you see the difference. This can be extremely useful even thought many OOP Developers resent it so much. A few days ago I had a conversation with some friends of mine about software architecture and to be honest, I’m not a huge fan of this area.
