# reducemonoid > Reduce with an associative operation [![Build Status](https://secure.travis-ci.org/phadej/reducemonoid.svg?branch=master)](http://travis-ci.org/phadej/reducemonoid) [![NPM version](https://badge.fury.io/js/reducemonoid.svg)](http://badge.fury.io/js/reducemonoid) [![Dependency Status](https://david-dm.org/phadej/reducemonoid.svg)](https://david-dm.org/phadej/reducemonoid) [![devDependency Status](https://david-dm.org/phadej/reducemonoid/dev-status.svg)](https://david-dm.org/phadej/reducemonoid#info=devDependencies) [![Code Climate](https://img.shields.io/codeclimate/github/phadej/reducemonoid.svg)](https://codeclimate.com/github/phadej/reducemonoid) ## Why For some reason *reducemonoid* is faster than `reduce` or `reduceRight`: ``` 100 elements reducemonoid x 407 ops/sec ±6.55% (82 runs sampled) native reduce x 190 ops/sec ±1.02% (90 runs sampled) native reduceRight x 168 ops/sec ±5.58% (73 runs sampled) underscore reduce x 162 ops/sec ±6.12% (82 runs sampled) underscore reduceRight x 164 ops/sec ±7.45% (78 runs sampled) lodash reduce x 188 ops/sec ±1.45% (89 runs sampled) lodash reduceRight x 189 ops/sec ±2.72% (90 runs sampled) Fastest is reducemonoid ``` ## API - `reduceMonoid(arr: Array a, operation: a -> a -> a, unit: a): a` - `reduceMonoid.reduceSemigroup(arr: NonEmptyArray a, operation: a -> a -> a): a`
