js-levenshtein-esm

This is a fork of js-levenshtein rewritten for ES module consumption.

A very efficient JS implementation calculating the Levenshtein distance, i.e. the difference between two strings.

Based on Wagner-Fischer dynamic programming algorithm, optimized for speed and memory

use a single distance vector instead of a matrix
loop unrolling on the outer loop
remove common prefixes/postfixes from the calculation
minimize the number of comparisons

Install

$ npm i -S js-levenshtein-esm

Usage

In Node:

1const levenshtein = require('js-levenshtein-esm');
2
3levenshtein('kitten', 'sitting'); // 3

In the browser:

1import levenshtein from 'https://unpkg.com/js-levenshtein-esm/js-levenshtein.js';
2
3levenshtein('kitten', 'sitting'); // 3
