    NanoEqual

    Ultra fast and compact implementation of deep equal without any production dependencies.

    Usage

    npm install nano-equal --save
    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:

    var a = {prop1: 'some', prop2: 'some'};
    var b = {prop2: 'some', prop1: 'some'};
     
    nanoEqual(a, b); // true

    But following of the array elements is important:

    var a = [1, 2, 3];
    var b = [3, 2, 1];
     
    nanoEqual(a, b); // false

    NaN values and some types of recursion are supported.
