$ npm install
$ npm test

usage

  require('nreseed').reseed();
  Math.random();

  const a = new Uint32Array(1);
  crypto.getRandomValues(a);

or

  const seeder = require('nreseed');

  const a = new seeder.PRNG();
  const b = new seeder.PRNG(0);

  a.random();
  b.random();

  b.setSeed(1);
  b.random();

  b.reseed();
  b.random();

  Math.random = function() {
    return b.random();
  };
