string-comparison-score

Tiny TypeScript library exposing Levenshtein (default) and Jaro–Winkler string comparison scores.

Usage:

import { compare, algorithms } from 'string-comparison-score';

// Default (Levenshtein normalized)
console.log(compare('kitten', 'sitting'));

// Use Jaro-Winkler
console.log(compare('martha', 'marhta', { algorithm: algorithms.jaroWinkler }));

API:

• compare(a, b, options?) — returns { score, distance? }.
• levenshteinDistance(a,b) — raw distance (integer).
• levenshteinScore(a,b) — { score, distance }.
• jaroWinklerScore(a,b) — { score }.
