Ultra fast and compact implementation of deep equal without any production dependencies.
npm install nano-equal --save
var nanoEqual = ;if//....
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';; // true
But following of the array elements is important:
var a = 1 2 3;var b = 3 2 1;; // false
NaN values and some types of recursion are supported.
