str-compare is a collection of algorithms to compare strings.

Installation

npm install str-compare

Algorithms

• Hamming distance

• Jaro-Winkler distance

• Levenshtein distance

• Sorensen / Dice coeficient

Basic usage

var strCompare = require('str-compare'),
    a = 'healed',
    b = 'healthy';

strCompare.jaro(a,b);
>>> 0.746031746031746

strCompare.jaroWinkler(a,b);
>>> 0.8476190476190476

strCompare.levenshtein(a,b);
>>> 3

strCompare.distanceToSimilarity(a, b, strCompare.levenshtein);
>>> 0.5714285714285714

s.sorensenDice(a,b);
>>> 0.5454545454545454
