Overwriting array properties.

Overwriting array properties.

@bobrenjc93 In my opinion that is the expected behavior, because we Recursively Object.assign():

deep_assign({a: [1]}, {a: []})

// should be similar to
{a: deep_assign([1], [])}

// which have to be the same as 
{a: Object.assign([1], [])}

(If Object {a: Array[1]} means {a: [1]})

This is consistent to the current undefined behavior.

I completely understand the recursive nature of this function. The question is what should be the base case. In my opinion, I think it only makes to recurse further if the value is a true object and not an array. In the event the value is not an object, the recursion should halt and behave the same way you'd expect a non recursive Object.assign for that particular value.

Perhaps it would be good to have the context under which this module was developed. I'm currently trying to use this module for a redux application and the behavior I described above was what I would expect in a recursive Object.assign module.

I think it only makes to recurse further if the value is a true object and not an array.

True Object is the crux of the matter: e.g Javascript also considers functions to be objects, and there seems no generally accepted definition for True Objects.

npm and bower contain myriad packages for merging/extending/… objects – most of them without a precise semantic. If you agree with me that Plain Objects are the one and only True Objects, schnittstabil/merge-options may meet your requirements.

As Object.assign does not distinguish Objects and Arrays I see no justification to do so in deep-assign.

Ah okay makes sense. merge-options is exactly what I need, I'll go use that. Thanks!
