Absurdum

"if all you have is a hammer, everything looks like a nail" - Maslow's Hammer

In this package, Array.prototype.reduce is the hammer

Why the Funky Name?

It's a play on the latin phrase Reductio ad absurdum

In logic, reductio ad absurdum (Latin for "reduction to absurdity"; or argumentum ad absurdum, "argument to absurdity") is a form of argument which attempts either to disprove a statement by showing it inevitably leads to a ridiculous, absurd, or impractical conclusion, or to prove one by showing that if it were not true, the result would be absurd or impossible.

It is often said that of the big trio map, filter, and reduce, the first two are redundant. In fact, it's trivial to implement both map and filter using reduce.

This library exists to take that concept to an absurd extreme by using reduce to implement as many different types of functional transforms as possible.

What's the Point?

• It's a challenge
• It's good practice
• It forces you to code/think in a functional manner
• Who cares, it's fun

...and just maybe, new patterns/practice will emerge from pushing reduce to its limits.

Usage

Import the desired namespace then call the operator from it

import { arrays } from 'absurdum';

const input = ['a', 'b', 'c', 'd'];
const output = arrays.reverse(input);
console.log(output);
// > ['d', 'c', 'b', 'a']
