Object copy

[Mameri, Fred (HBO)]

And maybe there should be a Object.move for value types...

Subject: Re: Object copy

I'd like Object.merge(source, dest), and Object.clone(source).

Object.clone would be best if it cloned almost any object, like more advanced clone functions.  This includes plain objects, arrays, instances of classes (preserving base class, etc.), regExp, promise, and ideally DOM nodes in browsers (along with anything else that can be cloned).  If something can't be cloned, including primitives and functions, it should throw an error.

Object.merge would be a much simpler "copy enumerable own properties" function.

Object.merge({a: 1}, {}); and Object.clone({a: 1}); would be equivalent, but they differ in most other cases.

Object.create() ?

It's not exactly cloning, but it'll probably work better than cloning in most cases.

Hi All

Do you know if it is planned or maybe in discussion for ES7 to have a simple clone system on objects ?

There are different notations, from :

 - jquery

Object.clone( [withDataAndEvents ] [, deepWithDataAndEvents ] )

( but only for DOM element )

 - underscore

_.clone(object)

( return the cloned object )

 - angular

angular.copy(source, [destination]);

(return the object, same as underscore, or copy into an optional destination )


Maybe an Object.copy([options?]) would be interesting ?
