Deep copying objects in Angular

Question

AngularJS has angular.copy() to deep copy objects and arrays.

Does Angular also have something like that?

Answer 1

I am faced with the problem of deep copying. angular.copy({}, factory) and angular.extend({}, factory) helps well for array or hashes objects, but when copying an object a calass, sometimes there may be problems with connected dependencies. I solved this problem so:

 copyFactory = (() ->
    resource = ->
      resource.__super__.constructor.apply this, arguments
      return
    this.extendTo resource
    resource
  ).call(factory)
