Functions are fundamental to code organization; they exist in all higher order programming languages. Generally, functional programming means using functions to the best effect for creating clean ...

A programming language that is based primarily on writing algorithms (functions). The syntax of functional programming (FP) is mathematical, and the languages are used for applications such as ...

Even with functional programming improvements in Java 8, Java remains an imperative, object-oriented programming language. It’s missing range types and other features that would make it more ...

Functional programming is a significant paradigm shift in the software world over the past 10 years. Slowly but surely, it has moved from a niche feature of a few uncommonly used languages to a ...

The object-oriented paradigm popularized by languages including Java and C++ has slowly given way to a functional programming approach that is advocated by popular Python libraries and JavaScript ...

Functional programming languages were, until recently, languages for computer science. Based on a pure mathematical approach to programming, they were the basis of much modern computer science ...

The previous code example illustrates four important points about functional programming: We can indeed think of the function f as a map between two sets of numbers. In terms of arr.map(f) where f is ...

A purely functional programming language is a functional language with an explicit way to manage effects like Haskell’s IO type. ... for example—and I consistently miss working in a pure language.

Figure 1. Functional JavaScript is available as an ebook (without DRM) from O'Reilly or as a paperback. Anyone who has followed my missives on programming have noted the varied exposure to ...

And in a more subtle way, functional programming has already ascended: by introducing functional features into conventional languages. The future, then, may not belong entirely to either style.
