n-gram

Get n-grams.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install n-gram

Use

import {bigram, trigram, nGram} from 'n-gram'

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

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

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

// Anything with a `.length` and `.slice` works: arrays too.
bigram(['alpha', 'bravo', 'charlie']) // [['alpha', 'bravo'], ['bravo', 'charlie']]
