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 ...

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 ...

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 ...

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 ...

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 ...

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.

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 ...

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 ...

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.
