primeval [![Build Status](https://travis-ci.org/lukeed/primeval.svg?branch=master)](https://travis-ci.org/lukeed/primeval)\n\n\u003e A tiny (128B) utility to check if a value is a prime number\n\nBased on the \"multiples of six\" approach – [check this out](http://mathforum.org/library/drmath/view/56068.html) for a quick explanation.\n\nAs of `3.0.0`, `primeval` is [extremely quick](#benchmarks) and actually usable within application settings.\n\n---\n\n#### Priors\n\n* `primeval@2.0.0` – implemented the [Agrawal–Kayal–Saxena (\"AKS\") Primality Test](https://en.wikipedia.org/wiki/AKS_primality_test)\u003cbr\u003eAKS is a _fully_ deterministic primality algorithm, but also incredibly slow.\u003cbr\u003eIts primary purpose was educational, so feel [free to explore](https://github.com/lukeed/primeval/tree/v2.0.0)!\n\n---\n\nThis module exposes three module definitions:\n\n* **ES Module**: `dist/primeval.mjs`\n* **CommonJS**: `dist/primeval.js`\n* **UMD**: `dist/primeval.min.js`\n\n## Install\n\n```\n$ npm install --save primeval\n```\n\n\n## Usage\n\n```js\nimport primeval from 'primeval';\n\nprimeval(2);   //=\u003e true\nprimeval(3);   //=\u003e true\nprimeval(17);  //=\u003e true\nprimeval(29);  //=\u003e true\nprimeval(25);  //=\u003e false\nprimeval(512); //=\u003e false\nprimeval(12);  //=\u003e false\nprimeval(1);   //=\u003e false\n\nprimeval(\"foobar\");   //=\u003e false\nprimeval(null);       //=\u003e false\nprimeval(NaN);        //=\u003e false\n```\n\n## API\n\n### primeval(num)\nReturns: `Boolean`\n\n#### num\n\nType: `Number`\n\nThe number that you want to check.\n\n\u003e **Note:** Any non-`Number` type will always return a `false` output.\n\n## Benchmarks\n\nThe `arguiot` case is the code provided in [`PR #2`](https://github.com/lukeed/primeval/pull/2) by [@arguiot](https://github.com/arguiot) :bowing_man:\n\nPurposefully excluding `primeval@2.0.0` as it's incredibly slow and not meant for actual use.\n\n```\n# Node v10.13.0\n\n# Primes\narguiot   x    875,571 ops/sec ±0.67% (91 runs sampled)\nprimeval  x  4,589,884 ops/sec
