small-prng

A fast, seedable replacement for Math.random().

Installation

npm i small-prng

Usage

Exported global function

The seed for the exported function random() is based on process.hrtime() when the module is first required.

const { random } = require('small-prng');
 
random();

Creating a seeded PRNG

To create a seeded PRNG, use the exported function prng(). Calling prng() without any arguments will use process.hrtime() as the seed.

const { prng } = require('small-prng');
 
const mySeed = 1;
const random = prng(mySeed);
 
random();
