Instead, functional programming prefers to take an existing variable and pass it through a “pipeline” (a function or functions) that transforms it into a new variable, leaving the original as-is.

To understand functional programming, we need to understand functions first. This might sound boring, but at the end of the day, it’s pretty insightful. So keep reading.

In Functional programming for Java developers, Part 1, I used JavaScript examples to get you started with five functional programming techniques: pure functions, higher-order functions, lazy ...

Functional programming might seem intimidating and overly academic at first, but once you get the hang of it, it helps you build more maintainable software, making the process more enjoyable.

Chapter 6: Functions and Functional Programming Substantial programs are broken up into functions for better modularity and ease of maintenance. Python makes it easy to define functions but also ...

In-Depth Functional Programming, the .NET Way The functional programming paradigm, which has been around for decades, has never gone out of style. In this two-part series, we look at Microsoft's ...
