We can clone an object by making a new object and then using the spread syntax to enumerate an object’s content inside it as its own. It seems like the right way, but it creates a shallow copy of the data. constobj={a:1,b:{c:2}}constclone={...obj};// creates a shallow cop...
This might happen when we don’t own the code, or when the object graph is so complicated that we wouldn’t finish our project on time if we focused on writing additional constructors or implementing theclonemethod on all classes in the object graph. So what can we do then? In that ca...
To deep clone an object ofEmployeeclass I have provided a deepClone()method which serializes the object to memory by using ByteArrayOutputStreaminstead of theFileOutputStreamand deserialises it back usingByteArrayInputStreaminstead of theFileInputStream.
