从前面所述可知,深拷贝与浅拷贝的区别主要在于 copy 的层次,浅拷贝 copy 的是第一层对象的引用,深拷贝需要 copy 深层次对象。So,以 deepcopy 层次 Object 为例子,要实现真正的深拷贝操作则需要通过遍历键来赋值对应的值,这个过程中如果遇到 Object 类型还需要再次进行遍历「同样的方法」。递归无疑了。来看波实现...

Adeep copyof an object is a copy whose properties donot share the same references(point to the same underlying values) as those of the source object from which the copy was made. As a result, when you change either the source or the copy, you can be assured you're not causing the ...
