MARC

A tiny Markov chain generator in JavaScript

Easily create Markov models from a given set of observations to generate random sequences of other potential observations.

Marc supports both time-homogeneous and higher-order Markov chains.

Usage

import Marc from 'marc';
// Our observations consist of four sentences from a rando's Twitter account
const observations = ['a sentence', 'another sentence', 'one more', 'and the last'];
// Give Mark the observations and tell it our token delimeter (' ')
const m = new Mark(observations, { delimeter: ' ', order: 0 }); // order = n - 1
// Generate a probable observation
const random = m.random();
