# object-clone

object-clone is a small package for cloning js objects

### Introduction

Normally when you assign an object to a new variable in Javascript, the original variable and the new variable will both point to the same object in memory. So for example:

```

var x = { y: { z: 0 } };

var test = x;

test.y.z = 2;

// x.y.z === 2

```

We don't always want the above behavior, and sometimes it's very inconvenient. This package adds an Object.clone method which returns a totally new object, not a reference to the original.

###Usage

```

require('object-clone');

var x = { y: { z: 0 } };

var test = Object.clone( x );

test.y.z = 2;

// test.y.z === 2

// x.y.z === 0

```

###Notes

* Test cases have been added in version 1.0.0 so it should be relatively reliable now

* Passing an object with circular references into Object.clone will now throw a TypeError instead of looping forever

###Version Updates

* 1.0.0: 

	* Added fixed and random tests

	* Fixed a bug that would attempt to call a constructor for null values

	* Added error handling for circular referenes

* 0.1.2: 

	* Enabled strict mode and fixed a bug where the key variable in the for..in loop was put in the global scope
