As a programmer, you probably want to write elegant, maintainable, scalable, predictable code. The principles of functional programming, or FP, can significantly aid in these goals.
Functional programming is a paradigm, or style, that values immutability, first-class functions, referential transparency, and pure functions. If none of those words makes sense to you, don't worry! We're going to break down all this terminology in this article.
The Core Principles of Functional Programming
Now that we've discussed what functional programming is, let's talk about the core principles behind FP.
