🧮 🇸🇪 Matematik

Mathematical helpers for JavaScript in browser or node

Purpose:

This list is growing and pretty much just helps suit my needs. If I find myself in need of another similar function, I'll add to it. If you'd like to add something to it, please do via pull request.

Why:

I would like to solve many of these mathematical dilemmas myself as I am learning, rather than simply pull in packages that others have made.

Useage:

npm i matematik

const math = require('matematik');
