: In FP, functions are treated like any other variable. You can pass them as arguments to other functions or return them as results.
If you want to write code like a functional programmer, you need to follow these basic rules: Functional Programming For Dummies
: A function is "pure" if it always gives the same output for the same input and has no side effects (it doesn't change anything outside itself, like updating a database). : In FP, functions are treated like any other variable
While it can be a challenging mindset shift, FP offers several major benefits: Fundamentals of functional programming | by Jonas Neumann While it can be a challenging mindset shift,
Functional programming (FP) is a style of coding where you treat software as a series of mathematical functions rather than a list of instructions. Instead of telling the computer to do something step-by-step, you describe what you want to happen. The Core Pillars of Functional Programming
