ECMAScript5 deep copy of object and arrays

Question

I'd hope to find an example code to do a deep copying of objects in ECMAScript5.

The copying should be able to clone

• Nested objects

• Nested arrays

• Nested objects in arrays (clone each array item individually)

Note: jQuery.extend() does not seem to handle case 3). Also, I'd hope to do this in clean ECMAScript. Quick googling did not bring up any worthy implementations.

Answer 1

I finally settled to jQuery.extend() as I couldn't find other good implementations
