[![Build Status](https://travis-ci.org/smelukov/nano-equal.svg?branch=master)](https://travis-ci.org/smelukov/nano-equal) [![npm version](https://badge.fury.io/js/nano-equal.svg)](https://badge.fury.io/js/nano-equal) ## NanoEqual Ultra fast and compact implementation of deep equal without any production dependencies. ### Usage ```shell npm install nano-equal --save ``` ```javascript var nanoEqual = require('nano-equal'); if (nanoEqual(a, b)) { //.... } ``` ### What is that? This is a compact and fast implementation of deep equal. Deep equal is an algorithm that comparing two values. If the values are a scalar (string, bool, number), then comparing will be performed thru === operator. If the values are an object (object, array, function), then comparing will be performed recursively. Following of the object properties is not important: ```javascript var a = {prop1: 'some', prop2: 'some'}; var b = {prop2: 'some', prop1: 'some'}; nanoEqual(a, b); // true ``` But following of the array elements is important: ```javascript var a = [1, 2, 3]; var b = [3, 2, 1]; nanoEqual(a, b); // false ``` > NaN values and some types of recursion are supported. ### Benchmark The list below is showing the performance comparison nano-equal with other libs: ``` nanoEqual: 1362.813ms underscore: 3791.308ms lodash: 7830.107ms nodejs: 8272.956ms ```
