NanoEqual

Simple and fast realization of deep equal.

How to use it?

var nanoEqual = require('nano-equal');

if(nanoEqual(a, b)) {
    //....
}

What is that?

This is a small and fast realization of deep equal, that supports CommonJS, AMD ang non-module definition.

Deep equal is an algorithm that comparing two values. If the values has a scalar types(string, bool, number), then comparing will be performed thru === operator.

If the values has an object types(object, array, function), then comparing will be performed recursively.

Following of the object properties is not important:

var a = {prop1: 'some', prop2: 'some'},
    b = {prop2: 'some', prop1: 'some'};

nanoEqual(a, b); //true

But following of the array elements is important:

var a = [1, 2, 3],
    b = [3, 2, 1];

nanoEqual(a, b); //false

As well, nano-equal supports NaN values and working correctly with recursive structures.
