Any better way to make a object into another object in javascript

Question

Oldobject = {'name':'Joe','age':12};
newObject = {'address':'XXX'};

I want to get result like :

{'name':'Joe','age':12,'address':'XXX' }

I use

Oldobject.address = newObject

Is there any graceful way to do this ?

Answer 1

for (var property in Oldobject) { 
    newObject[property] = Oldobject[property]; 
}

Answer 2

Use a for... in loop, like:

    for( var property in newObject ){
        OldObject[property] = newObject[property]
    }

This will put all of the stuff from newObject into oldObject.
