object-clone v1.0.0

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;
// 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
