Get n-grams in JavaScript.

Installation

npm:

npm install n-gram

Usage

var nGram = require('n-gram')

nGram.bigram('n-gram') // ['n-', '-g', 'gr', 'ra', 'am']
nGram(2)('n-gram') // ['n-', '-g', 'gr', 'ra', 'am']

nGram.trigram('n-gram') // ['n-g', '-gr', 'gra', 'ram']

nGram(6)('n-gram') // ['n-gram']
nGram(7)('n-gram') // []
